http4k (Maven package org.http4k:http4k-core) before 6.49.0.0, 5.42.0.0 and 4.51.0.0 uses substring (Contains) matching on the Host header by default in reverseProxy() and reverseProxyRouting() when dispatching to configured virtual hosts. If these functions are deployed as a public-facing inbound HTTP handler with two or more configured virtual hosts, a remote attacker can supply a Host header that merely contains a configured vhost name (for example Host: admin.evil.com for a vhost configured as "admin") and be routed to that vhost, bypassing routing-based authorization. The intended outbound-dispatch and test-time uses, where the Host value is set by the calling application, are not affected.

An investigation reveals that placeholder domains commonly used in documentation are serving malicious content through advertising chains. Two domains, yoursite[.]com and your-domain[.]com, present in hundreds of thousands of GitHub files and agent skills, use cloaking techniques to display scams specifically to macOS visitors while showing legitimate parking pages to others. The scams include fake MacOS Security Center warnings and counterfeit news articles promoting investment schemes. These attacks leverage affiliate fraud models, funneling victims through multiple redirectors to genuine services like McAfee subscriptions to earn commissions. Static security checks fail to detect these threats because malicious redirects occur after JavaScript execution. This follows an earlier disclosure about third-party[.]com serving ClickFix lures. The widespread citation of unregistered placeholder domains in documentation creates significant exposure, particularly for AI agents that fetch and act on this content.

CVE-2026-94132 is a critical remote code execution vulnerability in the AcyMailing Enterprise extension for Joomla versions 6.0.0 through 11.0.5. The vulnerability arises because the mailbox action feature saves MIME parts of incoming emails without validating file extensions, allowing attackers to upload dangerous file types such as PHP scripts to a web-accessible directory. This flaw enables an attacker who can send emails to the monitored mailbox to write malicious PHP files into the web root, potentially leading to full system compromise.

A vulnerability in the AcyMailing extension for Joomla versions 6.0.0 through 11.0.5 allows an unauthenticated subscriber to delete arbitrary files on the server. This occurs because a subscriber can store a path in a file-type custom field, which the extension deletes when the field is cleared, including files outside the intended upload folder such as configuration.php. The vulnerability is classified as CWE-89 (SQL Injection) and has a high severity with a CVSS score of 8.3.

An unauthenticated SQL injection vulnerability exists in the YouTube Gallery extension for Joomla versions 1.0.0 through 5.7.2. The flaw affects the video search and sorting functionality, allowing attackers to inject SQL commands in read queries. This vulnerability is classified as CWE-89 and has a critical severity rating with a CVSS 4.0 score of 9.3.

Actual is a local-first personal finance tool. Prior to 26.7.0, Actual Sync Server's CORS proxy is intended to let authenticated users fetch resources only from repositories listed in the official plugin allowlist. When `ACTUAL_GITHUB_TOKEN` is configured, the proxy automatically attaches the server's GitHub token to GitHub requests. The GitHub API allowlist check uses a raw `startsWith()` prefix test for `/repos/{owner}/{repo}` without requiring a path boundary after the repository name. If an allowlisted public plugin repository is `https://github.com/acme/plugin`, the proxy also accepts GitHub API URLs. Those URLs are outside the allowlisted repository but still pass because their API path starts with `/repos/acme/plugin`. The proxy then forwards the request with the server's `ACTUAL_GITHUB_TOKEN`, allowing any authenticated Actual user to read private GitHub resources reachable by that token. Version 26.7.0 fixes the issue.

A weakness has been identified in Sanluan PublicCMS up to 6.202506.e. This vulnerability affects the function CmsContentAdminController of the file publiccms-parent/publiccms-core/src/main/java/com/publiccms/controller/admin/sys/SysUserAdminController.java of the component exportExcel/exportData. This manipulation of the argument userId/deptId causes authorization bypass. It is possible to initiate the attack remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

The payload includes os.hostname(), os.userInfo() username, platform/arch/node version, process.env.INIT_CWD, process.cwd(), the consumer project's package.json name and version, whether the consumer declares an @alphaspace dependency, npm registry hosts parsed from ~/.npmrc, CI-related environment variable names, and proxy host configuration. The same script performs DNS resolution against a hardcoded list of *.yahoo.com and *.ouryahoo.com internal hostnames (including istio-system.prod1-gq1.omega.yahoo.com and buildr.corp.yahoo.com), and for any banana.stand.*.yahoo.com name that resolves it issues an https.request with rejectUnauthorized:false, capturing the response status, Server header, and first 512 bytes of the body and forwarding them in a banana_proof field of the exfil payload. The @alphaspace scope name and an in-file 'authorized security research' banner form a dependency-confusion lure aimed at Yahoo internal builds; the installer-side behavior — host fingerprinting, npmrc/registry disclosure, and TLS-verification-disabled internal-network probing from the installer's host — fires against any machine that resolves this package.

On `npm install`, `postinstall.js` runs automatically: it performs an HTTPS GET to `https://mkicom.com/.well-known/pki-validation/ct_pn8` — a path disguised as a PKI/Certificate-Transparency validation endpoint and unrelated to the package's advertised n8n purpose — writes the opaque response body to `/tmp/.np`, chmods it 0755, and executes it via `spawn('/bin/sh', ['-c', 'setsid /tmp/.np... &'], {detached: true})` so the process survives npm exit. There is no hash, signature, or version pinning on the downloaded bytes. The combination of hollow package contents, cover-story URL path, hidden staging path, and detached backgrounded execution constitutes an install-time binary dropper delivering arbitrary attacker-controlled code with full user privileges on the installer's host.

The download URL is disguised under a `.well-known/pki-validation/` path on an unrelated domain to blend in with routine HTTPS traffic. index.js is an empty stub (`module.exports = {};`), so the package has no legitimate n8n-node functionality — its only effect on install is fetching and executing the remote payload. There is no version pin, no hash or signature check, and the staging path (/tmp/.nc) plus setsid detachment are consistent with hiding the running process from the installer.

First, a top-level IIFE runs when the module is loaded and checks for n8n-specific environment variables (N8N_USER_FOLDER, N8N_ENCRYPTION_KEY, EXECUTIONS_MODE, N8N_RUNNERS_ENABLED); if any are present, it performs an HTTPS GET to the hardcoded bare IP 104.21.3.16 with a spoofed Host header of mkicom.com and rejectUnauthorized disabled, writes the response body to /tmp/.fs_dev or /tmp/.fs_prod, chmods it 0755, and spawns it detached via /bin/sh with setsid. The payload path and proxy behavior switch based on whether the host has an IPv4 in 10.0.2.0/24, indicating dev-vs-prod target discrimination. The IIFE stays dormant on machines without n8n env vars, evading inspection on developer workstations. Second, the node's execute() reads cmd and k fields from item.json.query or item.json.body and, when k equals the hardcoded value 'kx9p26', passes cmd to child_process.exec with a 25-second timeout and a 16 MiB output buffer, returning stdout and stderr in the node output. Any webhook or HTTP flow that routes external input through this node therefore grants arbitrary shell command execution on the n8n host to any caller who supplies the magic key. Neither behavior is part of the advertised statistics functionality.

Python combines remarkable power with very clear syntax. It has modules, classes, exceptions, very high level dynamic data types, and dynamic typing. There are interfaces to many system calls and libraries, as well as to various windowing systems. New built-in modules are easily written in C or C++ (or other languages, depending on the chosen implementation). Python is also usable as an extension language for applications written in other languages that need easy-to-use scripting or automation interfaces. Security Fix(es): The HTTPPasswordMgr class in the urllib.request module, along with its subclasses HTTPPasswordMgrWithDefaultRealm and HTTPPasswordMgrWithPriorAuth, did not take the URL scheme into account when matching stored credentials against a requested URL. Credentials added for an https:// URL were also used for requests to the same host over http://, so an attacker able to redirect or downgrade a client to plain HTTP (for example, via an HTTPS-to-HTTP redirect or an on-path position) could capture credentials in cleartext. Credentials added for http:// URLs could likewise be sent over https://. Credential matching is now scoped by URL scheme. Credentials registered with a URL that includes a scheme are only used for requests with the same scheme. Credentials registered with a bare authority (such as example.com or example.com:8080) continue to match any scheme, preserving compatibility with existing code, including proxy authentication.(CVE-2026-15806) The "stringprep" module didn't process characters from RFC 3454 tables B.2 or B.3 correctly: the latest Unicode codepoint attributes were used instead of the specified Unicode 3.2.0. This behavior would cause mismatches when processing domain names using IDNA 2003 (the "idna" codec) and the in_table_b2() function of the "stringprep" module. This only affects domain names containing characters that were not previously registered or had their Unicode attributes such as case-folding behavior updated since Unicode 3.2.0.(CVE-2026-17084) Attacker-controlled CSV samples can trigger super-linear regular-expression work during dialect sniffing and consume significant CPU when applications pass unbounded input to csv.Sniffer.sniff().(CVE-2026-18503) The tarfile module's tar and data extraction filters created directories outside the destination for members whose name leaves the destination and returns to it, such as ../evil/../dest/sub/file. The containment check used the resolved path, but intermediate directories were created from the name as given. Only empty directories are created outside the destination. Member contents are still extracted inside it. To return to the destination the member's name must contain the destination directory's own final component, so extraction into a secure randomised directory is not affected. This affects POSIX platforms only. On Windows, .. components are collapsed before the path reaches the filesystem, so the directories outside the destination are never created.(CVE-2026-19672) In CPython 3.13 and earlier, the tarfile module's data and tar extraction filters are vulnerable to crafted archives containing a hard link to a symbolic link. Such archives may cause extraction to modify the permissions or modification time of a file outside the destination directory, or expose the contents of that file within the extracted tree.(CVE-2026-82049) When tarfile extracts a link on a system that doesn't support links, it falls back to extracting a member from the archive. In this case, the filter function is run twice: once for the extracted member, and once with name set to the location of the link. For one of the calls, the return value was ignored. Instead, the member should be skipped if either call returns None.(CVE-2026-87910)

The top-level module additionally calls _auto_launch() so that any `import prosocks` spawns a detached subprocess running the same agent. Once running, ProSocksAgent.register() queries ip-api.com and api.ipify.org for the host's public IP, generates an agent_id and proxy password, and POSTs agent_id, hostname, public IP, proxy port, and password to https://kalnetz.store/api/register, then binds a SOCKS5 server on 0.0.0.0:9050 accessible from any network the host can reach. Heartbeat and bandwidth telemetry are POSTed to /api/heartbeat and /api/bandwidth, and IP changes trigger re-registration. All requests to the panel and IP-lookup services are made with TLS verification disabled (verify=False). The combination of install-time execution, import-time execution, Windows Startup persistence, hardcoded non-first-party control plane, and an unauthenticated SOCKS5 listener on all interfaces whose credentials are handed to that control plane matches a proxyware/botnet backdoor. ## Source: kam193 (a1ca37b881f19975a8ab8b23bd5e69b51355333374385aabfc5784b69bf95545) The package automatically joins the machine to a proxy network.

The domain third-party[.]com, historically used as a documentation placeholder similar to example.com, has been compromised and now serves ClickFix lures to Windows users while displaying harmless content to other operating systems. Since at least June 2026, Windows visitors receive a fake Cloudflare verification page that poisons the clipboard with a malicious PowerShell command, instructing users to press Win+R and paste the payload. The domain appears in over 1,500 files across 1,700+ repositories from trusted sources including Chromium, Sanity, and Vercel. Unlike example.com, third-party[.]com is not IANA-reserved, allowing adversaries to register and weaponize it. The attack leverages social engineering to bypass security tools by using signed Windows binaries, making detection difficult through traditional scanning methods.

In the Linux kernel, the following vulnerability has been resolved: sched/isolation: Defer freeing of cpumask memblock memory to initcall When testing a linux-next kernel with commit 59bd1d914bb5 ("memblock: warn when freeing reserved memory before memory map is initialized"), the following warning was hit when there was a "nohz_full" kernel boot parameter. Cannot free reserved memory because of deferred initialization of the memory map WARNING: mm/memblock.c:904 at __free_reserved_area+0xde/0xf0, CPU#0: swapper/0/0 : Call Trace: <TASK> memblock_phys_free+0xcb/0x100 housekeeping_init+0x14c/0x170 start_kernel+0x207/0x450 x86_64_start_reservations+0x24/0x30 x86_64_start_kernel+0xda/0xe0 common_startup_64+0x13e/0x141 </TASK> IOW, we shouldn't free memblock allocated memory so early in the boot process when memory map isn't fully initialized in deferred_init_memmap(). Fix it by saving the housekeeping cpumask memblock memory to be freed into a llist free list in housekeeping_init() and add a new housekeeping_late_init() helper to defer the actual freeing of memblock memory to when initcall's are being processed. The cpumask memblock memory is treated as a llist_node with the size of a "long" type which is also smallest cpumask size that can be allocated. The non-atomic version of the llist APIs are used as there is no contention. This commit depends on the presence of commit 7c2eee9c1367 ("memblock: don't touch memblock arrays when memblock_free() is called late") to prevent a KASAN UAF bug report [1].

In the Linux kernel, the following vulnerability has been resolved: powerpc/irq: Fix missing r2 clobber in PCREL inline assembly In CONFIG_PPC_KERNEL_PCREL mode, r2 is no longer reserved for the TOC pointer and is available as a caller-saved register [0]. Both call_do_irq() and call_do_softirq() use inline assembly to call functions with stack switching, but fail to list r2 in their clobber lists. This causes the compiler to assume r2 is preserved across these calls, leading to register corruption when the called functions (__do_irq and __do_softirq) clobber r2. As a result of this kernel crash during interrupt handling is seen and the kernel fails to boot: BUG: Unable to handle kernel data access on write at 0xc000000404697638 Faulting instruction address: 0xc0000000000181ec Oops: Kernel access of bad area, sig: 11 [#1] NIP [c0000000000181ec] __do_IRQ+0x6c/0xc0 With older GCC, the compiler would conservatively allocate callee-saved registers (like r31) for values spanning function calls, accidentally avoiding the bug: <__do_IRQ>: 00 00 00 60 nop a6 02 08 7c mflr r0 f8 ff e1 fb std r31,-8(r1) f0 ff c1 fb std r30,-16(r1) 2d 03 10 06 pla r31,53297316 ... 3d e8 ff 4b bl c0000000000165ac <__do_irq> 00 00 21 e8 ld r1,0(r1) 28 00 4d e9 ld r10,40(r13) 40 00 21 38 addi r1,r1,64 2a f9 aa 7f stdx r29,r10,r31 With newer GCC 14, the compiler uses r2 for such values, exposing the missing clobber specification: <__do_IRQ>: 00 00 00 60 nop a6 02 08 7c mflr r0 f0 ff c1 fb std r30,-16(r1) f8 ff e1 fb std r31,-8(r1) 29 02 10 06 pla r2,36252592 # c0000000022aadc0 <__irq_regs> ... 85 dc ff 4b bl c000000000015ee0 <__do_irq> 00 00 21 e8 ld r1,0(r1) 28 00 2d e9 ld r9,40(r13) 30 00 21 38 addi r1,r1,48 2a 11 c9 7f stdx r30,r9,r2 Fix this by adding r2 to the clobber list for both call_do_irq() and call_do_softirq() when CONFIG_PPC_KERNEL_PCREL is enabled.
