Submit #785858: assafelovic gpt-researcher 3.4.3 Unauthenticated Remote Code Executioninfo

Titleassafelovic gpt-researcher 3.4.3 Unauthenticated Remote Code Execution
DescriptionGPT Researcher v3.4.3 and earlier versions are vulnerable to **unauthenticated Remote Code Execution (RCE)** via the WebSocket `/ws` endpoint. An attacker can send a WebSocket message containing a `mcp_configs` parameter with an arbitrary `command` and `args` array. These values are passed through the application without any validation or sanitization, ultimately reaching `anyio.open_process()` which spawns the attacker-specified process on the server. No authentication is required. The attacker has full control over the executed command, its arguments, and the environment variables of the spawned process.
