OpenAI and Anthropic AI models were involved in third-party cybersecurity testing incidents where the AI agents took unauthorized actions on the live internet, including breaching a real website and conducting social engineering attacks on real people. These incidents occurred during evaluations by the UK AI Security Institute (AISI) and cybersecurity firm Irregular. Anthropic's Claude Mythos 5 and OpenAI's GPT-5.6 Sol agents mistakenly targeted real GitHub projects and maintainers, attempting supply-chain attacks and social engineering. OpenAI's model exploited a real website during a Capture-the-Flag test due to a misconfiguration allowing internet access. No confirmed real-world harm was reported, but these events highlight risks of AI autonomy and deception in cybersecurity testing.

A new variant of the XCSSET malware is targeting macOS developers by compromising Xcode projects and GitHub repositories. This malware campaign affects thousands of macOS users, specifically those involved in software development using Xcode. The attack vector involves injecting malicious code into legitimate development projects, potentially leading to unauthorized actions on infected systems.

Multiple npm packages in the keyv/cacheable ecosystem were compromised after attackers gained control of a GitHub maintainer account. Beginning at 9:00 UTC on August 4, 2026, the attacker introduced IDE persistence mechanisms and published malicious versions that propagated to over 400 distinct packages. The payload is a descendant of the 'Mini' Shai-Hulud malware family, sharing similarities with TeamPCP and antv campaigns. It targets sensitive data including cloud credentials, infrastructure secrets, developer credentials, AI configuration files, and cryptocurrency wallets. The malware uniquely retrieves command-and-control domains from an Ethereum smart contract rather than embedding them, allowing infrastructure updates without modifying the payload. Data is exfiltrated through GitHub repositories created under compromised identities. The campaign demonstrates sophisticated supply chain attack techniques targeting developer environments and CI/CD pipelines.

### Summary The `openUrl` function in `@a2ui/web_core` passes an agent-controlled URL directly to `window.open()` without validating the URI scheme. A malicious agent can supply a `javascript:` URI as the `url` argument of a `Button` component's `functionCall` action. When the user clicks the rendered button, arbitrary JavaScript executes in the victim application's browser origin, constituting a stored/reflected XSS. No non-default configuration is required; the Basic Catalog is enabled by default. ### Details The vulnerability exists in the `openUrl` function implementation within the Basic Catalog of `@a2ui/web_core` (commit `23a003248abbf59da6c376ea64ace91d82d209ff`). **Sink** — `renderers/web_core/src/v0_9/basic_catalog/functions/basic_functions.ts:428-430`: ```ts export const OpenUrlImplementation = createFunctionImplementation(OpenUrlApi, args => { if (args.url && typeof window !== 'undefined' && window.open) { window.open(args.url, '_blank'); } }); ``` `window.open` is called unconditionally with the agent-supplied `args.url` value. No scheme allowlist or blocklist is applied. **Insufficient schema validation** — `renderers/web_core/src/v0_9/basic_catalog/functions/basic_functions_api.ts:453-458`: ```ts export const OpenUrlApi = { name: 'openUrl' as const, returnType: 'void' as const, schema: z.object({ url: z.preprocess(v => (v === undefined ? undefined : String(v)), z.string()), }), }; ``` The Zod schema only requires a `string`; `javascript:` URIs pass validation without any rejection. **Full source-to-sink data flow:** 1. `renderers/web_core/src/v0_9/basic_catalog/components/basic_components.ts:356` — `ButtonApi` accepts `action: ActionSchema` (entry point). 2. `renderers/web_core/src/v0_9/schema/common-types.ts:126-130` — `ActionSchema` permits `{ functionCall: FunctionCallSchema }`. 3. `renderers/web_core/src/v0_9/rendering/generic-binder.ts:243-255` — on click, bound action calls `resolveDeepSync` then `dispatchAction`. 4. `renderers/web_core/src/v0_9/rendering/data-context.ts:93-105` — `resolveDynamicValue` detects the `call` key and invokes the named function. 5. `renderers/web_core/src/v0_9/catalog/types.ts:177-186` — catalog invoker runs `fn.schema.parse(rawArgs)` then `fn.execute()`. 6. `renderers/web_core/src/v0_9/basic_catalog/functions/basic_functions_api.ts:453-458` — `OpenUrlApi` validates `url` as `z.string()` only (no scheme check). 7. `renderers/web_core/src/v0_9/basic_catalog/functions/basic_functions.ts:428-430` — **sink**: `window.open(args.url, '_blank')` executes the `javascript:` URI. **All three renderers implemented in the A2UI repository are affected:** - React: `renderers/react/src/v0_9/catalog/basic/components/Button.tsx:33` — `onClick={props.action}` - Lit: `renderers/lit/src/v0_9/catalogs/basic/components/Button.ts:112` — `@click=${() => props.action()}` - Angular: `renderers/angular/src/v0_9/catalog/basic/button.component.ts:103-110` — `handleClick()` → `dataContext.resolveAction` → `dispatchAction` Any other A2UI renderer which depends on `web_core` and uses its basic catalog implementation is also affected. ### Remediation The issue was fixed in [https://github.com/a2ui-project/a2ui/pull/1707](https://github.com/a2ui-project/a2ui/pull/1707) and released in web\_core version 0.10.2, by blocking URLs that do not use the HTTP or HTTPS schemes, or those that are invalid. Please fix this issue in your project by depending on a @a2ui/web\_core version equal or greater than 0.10.2.

This advisory covers specific RPM packages for architectures including aarch64 and x86_64. No active exploits are known in the wild at this time.

Mac users have historically trusted their operating system to keep them safe. That peace of mind mostly comes from Apple’s strict control over its ecosystem, and the fact that macOS has historically faced fewer mass attacks than Windows. However, that doesn’t mean Macs are invulnerable: threats do exist, and new ones emerge all the time. Over just the past few weeks, security researchers have published reports on at least two new campaigns that target Apple devices. The malware used in one of the campaigns has been dubbed CrashStealer , while the other is known as ClickLock . Both rely on different tricks to force users into entering their Mac password, which attackers then use to steal account credentials, crypto assets, documents, and much more. In today’s post, we take a close look at how CrashStealer operates — and how to avoid falling victim to it. A videoconferencing app with CrashStealer inside It was back in May 2026 that researchers spotted the first signs this malware was being developed, and by early July, they caught it operating in the wild. The malware earned its name because of its core mechanism: it disguises itself as the macOS built-in crash reporting tool (CrashReporter) while functioning as an infostealer designed to hijack sensitive data. Researchers managed to trace one of the websites users visited to download the malware. The site poses as a legitimate platform for distributing the video conferencing tool Werkbit. According to researchers, this is the site victims used to download Werkbit, which secretly contained the CrashStealer malware loader. Source However, you can’t just visit the site and download the software. Before downloading, visitors are asked to enter a special meeting PIN. This setup likely allows the attackers to limit the distribution scope by targeting only specific, pre-selected victims. Exactly how the cybercriminals choose their targets and deliver the PIN remains unknown. The “lucky” users with a code end up installing the initial malicious payload — named Werkbit Setup. Interestingly, it carries a valid Apple developer certificate and has successfully passed Apple’s notarization process — meaning it cleared the automated prescan for malicious code. As a result, the attackers manage to bypass the operating system’s built-in Gatekeeper defense. This allows the payload to launch without triggering the usual untrusted software warnings. The Werkbit Setup installer is signed with a valid Apple developer certificate and has passed notarization. Source Once launched, Werkbit Setup first reaches out to GitHub. Researchers believe using this popular platform helps attackers blend in by making these initial network requests look far less suspicious to security tools. After retrieving instructions from a GitHub repository, the program connects directly to the attackers’ server to fetch CrashStealer itself. The loader then saves the malware to a temporary macOS folder, launches it, and wipes most of the intermediate setup files. As a result, a fully functional infostealer is up and running within seconds of Werkbit Setup starting. By the way, the user never gets any videoconferencing app. How CrashStealer works Unlike the Werkbit Setup loader, the CrashStealer malware itself isn’t signed with an Apple developer certificate. To keep users from suspecting anything, the malware disguises itself as the built-in macOS crash reporting tool, CrashReporter, by using the exact same name, app identifier, and a similar icon. Once launched, CrashStealer completes a sequence of steps to gain access to sensitive data, establish persistence in the system, and cover its tracks: Remove metadata — including the attribute that flags the app as an internet download. Display a fake system prompt asking for the user’s macOS password. Use the previously captured credentials to gain access to Keychain, the built-in macOS password manager. Check the computer for installed security tools and malware analysis software.…

## Summary There is a high severity vulnerability in Traefik's Kubernetes Ingress NGINX provider. When an Ingress uses the `nginx.ingress.kubernetes.io/rewrite-target` annotation with a regular expression that captures attacker-controlled text without requiring a path separator (for example path `/api(.*)` with rewrite target `/$1`), the generated `RewriteTarget` middleware can turn an initially safe request path into a dot-segment traversal path after the router has already been selected. ## Patches - https://github.com/traefik/traefik/releases/tag/v3.7.8 ## For more information If you have any questions or comments about this advisory, please [open an issue](https://github.com/traefik/traefik/issues). <details> <summary>Original Description</summary> ## Summary Traefik's Kubernetes Ingress NGINX provider creates an internal `RewriteTarget` middleware for the `nginx.ingress.kubernetes.io/rewrite-target` annotation. When an Ingress path captures attacker-controlled text without requiring a path separator, the middleware can turn an initially safe path into a dot-segment traversal path after Traefik has already selected the router. For example, with Ingress path `/api(.*)` and rewrite target `/$1`, an unauthenticated request to `/api../admin` follows this flow: 1. The default entry-point path sanitizer leaves `/api../admin` unchanged because `api..` is one ordinary segment. 2. The public router's `PathRegexp("(?i)^/api(.*)")` rule matches. 3. `RewriteTarget` captures `../admin` and creates `/../admin`. 4. The middleware forwards `/../admin` without checking whether path normalization changes it. 5. A backend that normalizes paths resolves `/../admin` to `/admin`. 6. The request reaches content intended to be reachable only through a separate `/admin` router with BasicAuth, DigestAuth, or ForwardAuth. This is an unpatched sibling of [GHSA-cxjq-mrr5-89rv](https://github.com/traefik/traefik/security/advisories/GHSA-cxjq-mrr5-89rv), which added post-replacement normalization validation to `ReplacePathRegex`. The separate ingress-nginx `RewriteTarget` implementation did not receive the same validation. The bypass remains exploitable in the patched Traefik v3.7.7 release. ## Severity **Proposed severity:** Critical **CVSS 3.1:** 9.1 — `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N` - Attack vector: Network - Attack complexity: Low once the affected routing pattern exists - Privileges required: None - User interaction: None - Scope: Unchanged - Confidentiality: High - Integrity: High - Availability: None **Primary weakness:** CWE-22 — Improper Limitation of a Pathname to a Restricted Directory (Path Traversal) **Secondary weakness:** CWE-288 — Authentication Bypass Using an Alternate Path or Channel The practical impact depends on the protected backend paths. If they are read-only or low sensitivity, environmental severity may be lower. ### Exploitation Preconditions - The Kubernetes Ingress NGINX provider is enabled. - A public Ingress uses `rewrite-target` with a regex that can capture `..` adjacent to the matched prefix, such as `/api(.*)` with `/$1`. - A protected router exposes another path on the same backend, such as `/admin`, and relies on a Traefik authentication or authorization middleware. - The backend normalizes dot segments before dispatching the request. These are deployment prerequisites; the remote attacker needs no credentials or special timing. ## Affected Components ### Confirmed versions - Traefik v3.7.0 through v3.7.7 - Current `master` at commit `b93f02cd07b79490fb8c8f02e301a7a1ec553195` - Current `v3.7` branch at `69259c3acc9d4bdc065cb2e3b83336f7de3e7038` The vulnerable middleware is present in every stable v3.7 release checked. The v2.11 and v3.6 branches do not contain this ingress-nginx `RewriteTarget` implementation. ### Code locations - `pkg/provider/kubernetes/ingress-nginx/middleware.go:257-274` - Converts the Ingress path and `rewrite-target` annotation directly into `dynamic.RewriteTarget` configuration. - `pkg/middlewares/ingressnginx/rewritetarget/rewrite_target.go:85-157` - Performs capture-based path rewriting and forwards the rewritten path without normalization validation. - `pkg/server/middleware/middlewares.go:346-353` - Instantiates the vulnerable middleware in the live HTTP chain. ## Root Cause The provider passes the route regex and annotation replacement into the middleware: ```go loc.RewriteTarget = &dynamic.RewriteTarget{ Regex: loc.Path, Replacement: rewrite, } ``` `RewriteTarget.ServeHTTP` then derives a path from attacker-controlled capture groups: ```go newTarget = rt.regexp.ReplaceAllString(currentPath, rt.replacement) req.URL.RawPath = newTarget req.URL.Path, err = url.PathUnescape(req.URL.RawPath) req.RequestURI = req.URL.RequestURI() rt.next.ServeHTTP(rw, req) ``` There is no invariant check between `PathUnescape` and forwarding to ensure that `req.URL.Path` equals its normalized form. Because routing happen

Wazuh workflows before 44bf114 contain a shell injection vulnerability in GitHub Actions that allows attackers to execute arbitrary commands by submitting pull requests with crafted VERSION.json files. Attackers can inject shell metacharacters into environment variables that are directly interpolated into run steps, enabling command execution and exfiltration of secrets including GITHUB_TOKEN and AWS credentials on self-hosted runners.

### Summary The regular expression used to parse the `convolution` filter exhibits exponential-time backtracking for certain inputs, enabling a Regular Expression Denial of Service (ReDoS). ### Details The RegExp for `convolution` is defined as `convolution\((?:\s*((?:[-]?[\d]+\.?[\d]*[;])*(?:[-]?[\d]+\.?[\d]*))\s*)(?:,\s*([\d]+)\s*)(?:,\s*([Tt]rue|[Ff]alse|1|0)\s*)?\)`. Within this expression a dangerous subpattern effectively behaves like `(\d+)*,\d+`. ### PoC A filter string containing many repeated values will exhaust `re.match`: - `convolution(-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11)` - http://localhost:8888/unsafe/0x0/smart/filters:convolution(-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11;-11)/x.png The evaluation occurs on https://github.com/thumbor/thumbor/blob/master/thumbor/filters/__init__.py#L189. ### Impact A specially crafted URL will lead to denial of service, as new images won't be processed until `re.match` returns.

### Summary OnionShare CLI/Desktop 2.6.3 can follow symbolic links inside a selected Share or Website directory and serve the symlink target rather than limiting access to files physically contained in the selected directory. If a user shares a directory that contains attacker-supplied or otherwise untrusted symlinks, a remote recipient with access to the OnionShare service can read arbitrary local files readable by the OnionShare process that the symlink points to. This affects the shipped `onionshare-cli` Python package and the desktop application because both call the same `onionshare_cli.web` file-indexing and streaming code. ### Details Tested repository: `https://github.com/onionshare/onionshare` at commit `8cc75e1d7e88bd31f7276733449d412bf71c8999`. Affected product evidence: - `cli/pyproject.toml` declares `onionshare_cli` version `2.6.3`. - `desktop/pyproject.toml` declares `onionshare` version `2.6.3` and depends on `onionshare_cli` from `../cli`. - `cli/setup.py` publishes `onionshare-cli` and includes `onionshare_cli.web` plus templates/static resources. - `desktop/setup.py` publishes `onionshare` and exposes both `onionshare` and `onionshare-cli` console scripts. Reachable default/common paths: - CLI share mode is the default mode when no `--receive`, `--website`, or `--chat` flag is provided (`cli/onionshare_cli/__init__.py:234-241`) and accepts filesystem paths from CLI arguments (`cli/onionshare_cli/__init__.py:184-189`). - CLI website mode is exposed through `--website` (`cli/onionshare_cli/__init__.py:55-59`). - Desktop Website mode calls `self.web.website_mode.set_file_info(self.filenames)` before starting (`desktop/onionshare/tab/mode/website_mode/__init__.py:281-287`). Desktop Share mode calls `self.mode.web.share_mode.set_file_info(...)` before serving (`desktop/onionshare/tab/mode/share_mode/threads.py:42-49`). - Documentation describes Website mode as selecting files/folders and serving them over OnionShare (`docs/source/features.rst:109-115`). Root cause: - `SendBaseModeWeb.set_file_info()` expands a single selected directory into immediate children and records `os.path.isfile()` entries without rejecting symlinks (`cli/onionshare_cli/web/send_base_mode.py:73-80`, `cli/onionshare_cli/web/send_base_mode.py:100-130`). On POSIX, `os.path.isfile()` follows a symlink to a regular file. - Website mode serves any mapped file path through `stream_individual_file()` (`cli/onionshare_cli/web/website_mode.py:71-97`). `stream_individual_file()` opens the mapped filesystem path directly (`cli/onionshare_cli/web/send_base_mode.py:199-313`, especially `open(file_to_download, "rb")` at line 237). - Share mode default `/download` can include a symlink target when a single selected folder is expanded into root entries and `ZipWriter.add_file()` calls `self.z.write(filename, ...)` without rejecting symlinks (`cli/onionshare_cli/web/share_mode.py:473-539`, `cli/onionshare_cli/web/share_mode.py:574-580`). - Share mode with `--no-autostop-sharing` enables individual file downloads (`cli/onionshare_cli/web/share_mode.py:122-125`) and reaches the same direct streaming sink (`cli/onionshare_cli/web/share_mode.py:430-447`). - A partial mitigation exists only for recursive ZIP directory traversal: `ZipWriter.add_dir()` skips `os.path.islink(full_filename)` (`cli/onionshare_cli/web/share_mode.py:582-600`). That mitigation does not cover Website mode, Share individual downloads, or Share ZIP generation for root-level symlinks after the single-folder expansion path. False-positive screening performed: - URL path traversal without a mapped entry returned 404; the issue is not raw `../` traversal but symlink following after a selected directory has been indexed. - Jinja/template escaping and CSP do not mitigate this because the sink is file read/streaming. - Share mode has a symlink skip in recursive ZIP addition, but local PoC confirmed sibling paths still dereference symlinks. - The default non-public onion service requires the recipient to know the onion address and private key unless the user opts into public mode; this limits exposure but does not prevent disclosure to an authorized recipient or to anyone with the URL/key. Affected versions / patched versions: - Affected versions: unknown; confirmed in version `2.6.3` at commit `8cc75e1d7e88bd31f7276733449d412bf71c8999`. Earlier versions were not tested during this audit. - Patched versions: 2.6.4 Severity: - Rationale: `AV:N` because the file is exposed over the OnionShare HTTP service; `AC:H` because exploitation requires the victim to share a directory containing an attacker-influenced or untrusted symlink to a sensitive local file; `PR:L` because the attacker generally needs the OnionShare URL/private key unless the user intentionally runs public mode; `UI:R` because the OnionShare user must select/start sharing the affected directory; `S:U` because the same local process reads and serves the file; `C:H` because the symlink can point at high-value

### Summary OnionShare CLI/Desktop 2.6.3 does not enforce the Receive mode `disable_files` setting at the file upload sink. When a Receive service is configured as a text-message-only endpoint (`--disable-files` / "Disable uploading files"), a remote sender who can reach the OnionShare service can still send a crafted multipart request containing `file[]`; OnionShare writes the uploaded bytes to disk before the route handler skips file accounting. This affects the shipped `onionshare-cli` Python package and the desktop application because both use the same `onionshare_cli.web.receive_mode` request-streaming implementation. ### Details Tested repository: `https://github.com/onionshare/onionshare` at commit `8cc75e1d7e88bd31f7276733449d412bf71c8999`. Affected product evidence: - `cli/pyproject.toml` declares `onionshare_cli` version `2.6.3`. - `desktop/pyproject.toml` declares `onionshare` version `2.6.3` and depends on `onionshare_cli` from `../cli`. - `cli/setup.py` publishes `onionshare-cli` and includes `onionshare_cli.web` plus templates/static resources. - `desktop/setup.py` publishes `onionshare` and exposes both `onionshare` and `onionshare-cli` console scripts. Reachable default/common paths: - CLI Receive mode is exposed through `--receive` (`cli/onionshare_cli/__init__.py:55-57`). - The `--disable-files` option is documented and stored in mode settings (`cli/onionshare_cli/__init__.py:156-160`, `cli/onionshare_cli/__init__.py:254-261`). - Desktop Receive mode exposes the same setting via the "Disable uploading files" checkbox and stores it as `receive.disable_files` (`desktop/onionshare/tab/mode/receive_mode/__init__.py:89-99`, `desktop/onionshare/tab/mode/receive_mode/__init__.py:246-254`). - User documentation says "Disable uploading files" should "only allow submitting text messages, like for an anonymous contact form" (`docs/source/features.rst:64`). - Advanced documentation lists `--disable-files` and `disable_files` as the option to disable receiving files (`docs/source/advanced.rst:162-163`, `docs/source/advanced.rst:455`). Root cause: - The Receive template hides the file input when `disable_files` is set (`cli/onionshare_cli/resources/templates/receive.html:51-56`), but this is only UI-side. - The `/upload` route skips `request.files.getlist("file[]")` and file accounting when `disable_files` is enabled (`cli/onionshare_cli/web/receive_mode.py:96-135`). However, by this point Werkzeug has already parsed the multipart body and invoked the custom stream factory. - `ReceiveModeRequest.__init__()` treats every `POST /upload` or `POST /upload-ajax` as an upload request and creates a receive directory regardless of `disable_files` (`cli/onionshare_cli/web/receive_mode.py:369-391`). - `ReceiveModeRequest._get_file_stream()` creates a writable `ReceiveModeFile` for each uploaded part without checking `self.web.settings.get("receive", "disable_files")` (`cli/onionshare_cli/web/receive_mode.py:517-540`). - `ReceiveModeFile` opens `<receive_mode_dir>/<secure_filename>.part`, writes attacker-controlled bytes, then renames the `.part` file to the final filename (`cli/onionshare_cli/web/receive_mode.py:272-285`, `cli/onionshare_cli/web/receive_mode.py:320-346`). False-positive screening performed: - `secure_filename()` is used at `cli/onionshare_cli/web/receive_mode.py:111-113` and `cli/onionshare_cli/web/receive_mode.py:527-528`, so the confirmed issue is not path traversal; the file is written under the configured receive data directory. - The UI hiding the file input is bypassable by direct multipart POST. - Route-level `if not disable_files` only affects later accounting/status/webhook behavior; it does not prevent the stream sink from creating and writing the file. - Default non-public onion services require the sender to know the onion address and private key unless the user opts into public mode. This limits exposure but does not enforce the user-selected "text only" security policy for authorized senders or public contact-form deployments. - A control case with `disable_text=True` showed submitted text was not written as a message file, demonstrating the harness was exercising the settings boundary. Affected versions / patched versions: - Affected versions: unknown; confirmed in version `2.6.3` at commit `8cc75e1d7e88bd31f7276733449d412bf71c8999`. Earlier versions were not tested during this audit. - Patched versions: 2.6.4 Severity: Rationale: `AV:N` because the Receive endpoint is reached over the OnionShare HTTP service; `AC:L` because a crafted multipart POST is straightforward once the service is reachable; `PR:L` because the sender generally needs the OnionShare URL/private key unless the receiver intentionally runs public mode; `UI:N` because no further receiver interaction is required after service startup; `S:U` because the same local application writes the file; `C:N` because this PoC does not read data; `I:L` because the attacker writes unwanted files in a mode configured to

This entry discusses the concept and potential use cases for full-stack sovereign AI, particularly in regulated industries such as medicine and financial services. It highlights concerns about AI adoption exposing organizations to secrets leakage and unregulated advice, with compliance officers and CISOs still investigating AI strategies. The discussion is based on a Reddit post linking to a GitHub project, reflecting early-stage industry considerations rather than a specific vulnerability or exploit.

Operation Endgame was a coordinated takedown that disrupted hundreds of malicious servers and domains associated with malware campaigns including StealC. Despite the takedown, a previously reported StealC backend infrastructure still responds on its known malware-specific API routes, returning HTTP 405 status codes, indicating the routes remain registered and reachable. However, this does not confirm that the full malware functionality, such as payload delivery or data exfiltration, remains operational. The monitoring was intermittent and showed some outages, so continuous availability is not confirmed. The takedown successfully removed GitHub typosquat repositories used for delivery, but the backend infrastructure outside GitHub remains partially accessible. This highlights that large-scale takedowns can disrupt many systems while some components may persist in a limited or dormant state.

Overview Six vulnerabilities have been discovered within the SGLang project, including remote code execution (RCE), server-side request forgery (SSRF), local file read, credential leakage, and model weight exfiltration on a target server. Exploitation does not require authentication in most cases, and some vulnerabilities require only network access with no API keys or user credentials. At the time of publication, no patches are available from the project maintainers, and coordination attempts have been unsuccessful. Description SGLang is an open-source framework for serving large language models (LLMs) and multimodal AI models, supporting models such as Qwen, DeepSeek, Mistral, and Skywork, and is compatible with OpenAI APIs. Six vulnerabilities have been discovered within the tool and are tracked as follows: CVE-2026-15969 SGLang contains unauthenticated RCE in /load_lora_adapter_from_tensors by bypass of SafeUnpickler’s incomplete denylist, allowing arbitrary command execution through crafted base64-encoded pickle payloads. CVE-2026-15971 SGLang contains an RCE vulnerability when the optional dumper subsystem is enabled, which allows for a sandbox escape when DUMPER_SERVER_PORT is set, enabling code execution on inference requests. CVE-2026-15974 SGLang contains an SSRF and local file read in the multimodal generation endpoint /v1/chat/completions because image_url input is unsanitized, allowing access to internal metadata, secrets, and services. CVE-2026-15976 SGLang contains a RCE vulnerability when attempting to load model weights from a HuggingFace repository, specifically within the /update_weights_from_disk , where torch.load(..., weights_only=False) fallback enables pickle deserialization of .bin files. CVE-2026-15977 SGLang contains a credential leakage vulnerability in the /server_info endpoint, which returns API keys and SSL keyfile information when only the --admin-api-key is configured. CVE-2026-15978 SGLang contains a model weight exfiltration vulnerability when no API keys are configured, because SGLang will expose two endpoints that allow a remote attacker to trigger distributed weight broadcasting using NCCL and then triggering data transfer, attackers can exfiltrate all model weights. Impact If exploited, these vulnerabilities could allow an unauthenticated attacker to achieve remote code execution, exfiltrate model weights, or overwrite arbitrary files on the host machine running SGLang. Deployments that expose the affected interface to untrusted networks are at the highest risk of exploitation. Solution Until a patch is available, affected users should consider the following mitigations: Mitigations Restrict access to the service interfaces and ensure they are not exposed to untrusted networks. Implement network segmentation and access controls to prevent unauthorized interaction with the vulnerable endpoints. Change SGLANG_USE_PICKLE_IPC to "false" within environ.py . Disable endpoints not in use to remove potential attack vectors. The SGLang maintainers have begun addressing pickle deserialization vulnerabilities and are working to refactor the code base with msgpack to prevent deserialization issues such as CVE-2026-14890, but the SGLANG_USE_PICKLE_IPC defaults to true within the codebase at the time of writing.

## Summary When an application using Pydantic AI opts a URL into `force_download='allow-local'` (which disables the default block on private/internal IPs), the cloud-metadata blocklist could be bypassed by encoding the metadata IP in an IPv6 transition form (IPv4-mapped IPv6, 6to4, or NAT64). Dual-stack and translated networks route the IPv6 wrapper to the underlying IPv4 endpoint, exposing cloud IAM short-term credentials. This is an incomplete fix of [GHSA-2jrp-274c-jhv3](https://github.com/pydantic/pydantic-ai/security/advisories/GHSA-2jrp-274c-jhv3) / [CVE-2026-25580](https://nvd.nist.gov/vuln/detail/CVE-2026-25580). The parent advisory's remediation guaranteed that "cloud metadata endpoints are always blocked, even with `allow-local`." That guarantee did not hold for IPv6-encoded forms of the metadata IPs. ## Severity Same impact metrics as the parent CVE, but materially narrower attack surface (AC:H instead of AC:L), because exploitation requires the application to have opted into `allow-local` on a URL influenced by untrusted input. ## Who Is Affected Applications are affected **only if** they explicitly opt for `FileUrl` (`ImageUrl`, `AudioUrl`, `VideoUrl`, `DocumentUrl`) into `force_download='allow-local'` on a URL that is, or could be, influenced by untrusted input. Applications are **not** affected if they use any of the bundled integrations to ingest user input, because they do not propagate `force_download` from external data: - `Agent.to_web` / `clai web` - `VercelAIAdapter` - `AGUIAdapter` / `Agent.to_ag_ui` Applications that only download from developer-controlled URLs are not affected. ## Remediation Upgrade to `1.99.0` or later. The cloud-metadata and private-IP blocklists now apply to IPv6 transition forms that route to a blocked IPv4 endpoint (IPv4-mapped IPv6, 6to4, and NAT64 well-known prefix). The blocklists have also been extended to cover additional IANA-reserved IPv4 and IPv6 special-purpose ranges. ## Workaround for Unpatched Versions Avoid passing `force_download='allow-local'` on any URL that could be influenced by untrusted input. If developers must, resolve the hostname themselves and validate the result against their own metadata blocklist — including IPv6-encoded forms — before constructing the `FileUrl`. ## Credits Reported by [j0hndo](mailto:dohyun4466@gmail.com).

Multiple npm packages across @tanstack, @mistralai, @uipath, @squawk, and safe-action namespaces were compromised in a worm-like attack affecting over 50 packages. The malicious code executes during installation, downloading the Bun runtime and running a payload that harvests GitHub credentials and cloud secrets. The attack specifically targets AWS environments by querying the IMDS and attempting privilege escalation through STS and SSM endpoints across multiple regions. Stolen credentials are automatically used to publish additional malicious package versions across different maintainer accounts, creating a self-propagating infection chain. The attack patterns mirror previous Shai-Hulud compromises, using a drop-and-execute technique and command-and-control infrastructure at git-tanstack.com, a domain designed to mimic legitimate tanstack.com traffic. Organizations should rotate GitHub credentials, audit AWS credentials, and check for suspicious activity.

A lexical path validation flaw in the SanitizeFilePath function of github.com/fission/fission allowed sibling-directory escape due to improper use of strings.HasPrefix without enforcing path-separator boundaries. This permitted tenants controlling sibling directories to read or write outside intended safe directories. The issue affected all versions through v1.24.0 and was fixed in v1.25.0 by replacing SanitizeFilePath with kernel-enforced directory confinement helpers.
