Quorum Cyber identifies two new NodeSnake RAT variants, strongly attributed to Interlock ransomware, impacting UK higher education and local government.

### Summary A permission verification flaw in Navidrome allows any authenticated regular user to bypass authorization checks and perform administrator-only transcoding configuration operations, including creating, modifying, and deleting transcoding settings. ### Details Navidrome supports transcoding functionality which, although disabled by default, should restrict configuration operations to administrators only. However, the application fails to properly validate whether a user has administrative privileges when handling transcoding configuration requests. The vulnerability exists in the API endpoints that manage transcoding settings. When a regular user sends requests to these endpoints, the application processes them without verifying if the user has administrative privileges, despite the JWT token clearly indicating the user is not an administrator (`"adm":false`). The affected endpoints include: - `POST /api/transcoding` (Create transcoding configuration) - `PUT /api/transcod...

Cisco Talos uncovers CyberLock ransomware, Lucky_Gh0$t, and Numero malware masquerading as legitimate software and AI tool installers. Learn…

Cybersecurity researchers have taken the wraps off an unusual cyber attack that leveraged malware with corrupted DOS and PE headers, according to new findings from Fortinet. The DOS (Disk Operating System) and PE (Portable Executable) headers are essential parts of a Windows PE file, providing information about the executable. While the DOS header makes the executable file backward compatible

Fortinet spots new malware that corrupts its own headers to block forensic analysis, hide behavior, and communicate with its C2 server.

Cisco Talos has uncovered new threats, including ransomware like CyberLock and Lucky_Gh0$t, and a destructive malware called Numero, all disguised as legitimate AI tool installers to target victims.

### Summary The vLLM backend used with the /v1/chat/completions OpenAPI endpoint fails to validate unexpected or malformed input in the "pattern" and "type" fields when the tools functionality is invoked. These inputs are not validated before being compiled or parsed, causing a crash of the inference worker with a single request. The worker will remain down until it is restarted. ### Details The "type" field is expected to be one of: "string", "number", "object", "boolean", "array", or "null". Supplying any other value will cause the worker to crash with the following error: RuntimeError: [11:03:34] /project/cpp/json_schema_converter.cc:637: Unsupported type "something_or_nothing" The "pattern" field undergoes Jinja2 rendering (I think) prior to being passed unsafely into the native regex compiler without validation or escaping. This allows malformed expressions to reach the underlying C++ regex engine, resulting in fatal errors. For example, the following inputs will crash the wo...
