| Description: | | BerriAI LiteLLM is a proxy service from the BerriAI organization that unifies large language model interfaces. LiteLLM versions 1.74.2 through before 1.83.7 contain a command injection vulnerability. The vulnerability stems from two endpoints used to preview MCP servers accepting the complete server configuration in the request body, including the command, arguments, and environment fields used by the stdio transport. When invoked with a stdio configuration, the endpoints attempt to connect and spawn a child process. The endpoints are protected only by a valid proxy API key without role checks, allowing any authenticated user to run arbitrary commands. |
