Mattermost versions 10.5.x <= 10.5.1, 10.4.x <= 10.4.3, 9.11.x <= 9.11.9 fail to prevent Wrangler posts from triggering AI responses. This vulnerability allows users without access to the AI bot to activate it by attaching the activate_ai override property to a post via the Wrangler plugin, provided both the AI and Wrangler plugins are enabled.

Mattermost versions 10.5.x <= 10.5.1, 10.4.x <= 10.4.3, 9.11.x <= 9.11.9 fail to check the "Allow Users to View Archived Channels" configuration when fetching channel metadata of a post from archived channels, which allows authenticated users to access such information when a channel is archived.

Cheap Android smartphones manufactured by Chinese companies have been observed pre-installed with trojanized apps masquerading as WhatsApp and Telegram that contain cryptocurrency clipper functionality as part of a campaign since June 2024. While using malware-laced apps to steal financial information is not a new phenomenon, the new findings from Russian antivirus vendor Doctor Web point to

The U.S. government funding for non-profit research giant MITRE to operate and maintain its Common Vulnerabilities and Exposures (CVE) program will expire Wednesday, an unprecedented development that could shake up one of the foundational pillars of the global cybersecurity ecosystem. The 25-year-old CVE program is a valuable tool for vulnerability management, offering a de facto standard to

A critical resource that cybersecurity professionals worldwide rely on to identify, mitigate and fix security vulnerabilities in software and hardware is in danger of breaking down. The federally funded, non-profit research and development organization MITRE warned today that its contract to maintain the Common Vulnerabilities and Exposures (CVE) program -- which is traditionally funded each year by the Department of Homeland Security -- expires on April 16.

Cybercriminals capitalize on tax preparation stress, technology sprawl, and lax communications. Accounting teams can't afford to treat cybersecurity as an afterthought.

## Advisory The management of JetStream assets happens with messages in the `$JS.` subject namespace in the system account; this is partially exposed into regular accounts to allow account holders to manage their assets. Some of the JS API requests were missing access controls, allowing any user with JS management permissions in any account to perform certain administrative actions on any JS asset in any other account. At least one of the unprotected APIs allows for data destruction. None of the affected APIs allow disclosing stream contents. ### Affected versions NATS Server: * Version 2 from v2.2.0 onwards, prior to v2.11.1 or v2.10.27 ----- ## Original Report (Lightly edited to confirm some supposition and in the summary to use past tense) ### Summary nats-server did not include authorization checks on 4 separate admin-level JetStream APIs: account purge, server remove, account stream move, and account stream cancel-move. In all cases, APIs are not properly restricted t...

A lawsuit over the Trump administration’s infamous Houthi Signal group chat has revealed what steps departments took to preserve the messages—and how little they actually saved.

### Impact This report is to highlight a vulnerability in XGrammar, a library used by the structured output feature in vLLM. The XGrammar advisory is here: https://github.com/mlc-ai/xgrammar/security/advisories/GHSA-389x-67px-mjg3 The [xgrammar](https://xgrammar.mlc.ai/docs/) library is the default backend used by vLLM to support structured output (a.k.a. guided decoding). Xgrammar provides a required, built-in cache for its compiled grammars stored in RAM. xgrammar is available by default through the OpenAI compatible API server with both the V0 and V1 engines. A malicious user can send a stream of very short decoding requests with unique schemas, resulting in an addition to the cache for each request. This can result in a Denial of Service by consuming all of the system's RAM. Note that even if vLLM was configured to use a different backend by default, it is still possible to choose xgrammar on a per-request basis using the `guided_decoding_backend` key of the `extra_body` field ...
