### Impact The `fetch()` API supports chained HTTP encoding algorithms for response content according to RFC 9110 (e.g., Content-Encoding: gzip, br). This is also supported by the undici decompress interceptor. However, the number of links in the decompression chain is unbounded and the default maxHeaderSize allows a malicious server to insert thousands compression steps leading to high CPU usage and excessive memory allocation. ### Patches Upgrade to 7.18.2 or 6.23.0. ### Workarounds It is possible to apply an undici interceptor and filter long `Content-Encoding` sequences manually. ### References * https://hackerone.com/reports/3456148 * https://github.com/advisories/GHSA-gm62-xv2j-4w53 * https://curl.se/docs/CVE-2022-32206.html

The Black Lotus Labs team at Lumen Technologies said it null-routed traffic to more than 550 command-and-control (C2) nodes associated with the AISURU/Kimwolf botnet since early October 2025. AISURU and its Android counterpart, Kimwolf, have emerged as some of the biggest botnets in recent times, capable of directing enslaved devices to participate in distributed denial-of-service (DDoS)

Researchers have discovered VoidLink, a sophisticated new Linux malware framework designed to infiltrate AWS, Google Cloud, and Azure. Learn how this Chinese-affiliated toolkit uses adaptive stealth to stay hidden.

### Impact We fixed with [CVE-2023-2017](https://github.com/advisories/GHSA-7v2v-9rm4-7m8f) Twig filters to only be executed with allowed functions. However there was a regression that lead to an array and array crafted PHP Closure not checked being against allow list for the map(...) override ### Patches Patched in 6.7.6.1 ### Workarounds Install the security plugin

### Impact html2pdf.js contains a cross-site scripting (XSS) vulnerability when given a text source rather than an element. This text is not sufficiently sanitized before being attached to the DOM, allowing malicious scripts to be run on the client browser and risking the confidentiality, integrity, and availability of the page's data. Example attack vector: ```js import html2pdf from 'html2pdf.js/src/index.js'; const maliciousHTML = '<img src=x onerror="alert(document.cookie)">'; html2pdf(maliciousHTML); // or html2pdf().from(maliciousHTML); ``` ### Patches This vulnerability has been fixed in html2pdf.js@0.14.0 to sanitize text sources using DOMPurify. There are no other breaking changes in this version. ### Workarounds Users of earlier versions of html2pdf.js must safely sanitize any text before using it as a source in html2pdf.js. ### References - Initial report: https://github.com/eKoopmans/html2pdf.js/issues/865 - Fix: https://github.com/eKoopmans/html2pdf.js/pull/877, [v0....

### Impact The screenshot images were served directly by the HTTP server without proper access control. This could allow an unauthenticated user to access screenshots after guessing their filename. ### Patches * https://github.com/WeblateOrg/weblate/pull/17516 ### References Thanks to Lukas May and Michael Leu for reporting this.

AI agents have quickly moved from experimental tools to core components of daily workflows across security, engineering, IT, and operations. What began as individual productivity aids, like personal code assistants, chatbots, and copilots, has evolved into shared, organization-wide agents embedded in critical processes. These agents can orchestrate workflows across multiple systems, for example:

A hacker claims a full breach of Russia’s Max Messenger, threatening to leak user data and backend systems if demands are not met.

Security experts have disclosed details of an active malware campaign that's exploiting a DLL side-loading vulnerability in a legitimate binary associated with the open-source c-ares library to bypass security controls and deliver a wide range of commodity trojans and stealers. "Attackers achieve evasion by pairing a malicious libcares-2.dll with any signed version of the legitimate ahost.exe (
