vLLM versions prior to 0.26.0 have a vulnerability where malformed API requests cause error messages to leak sensitive internal information such as file paths, line numbers, OS username, home directory, Python version, and internal package structure. This occurs because the error handler converts validation exceptions to strings that include traceback details, which are insufficiently sanitized before being returned in HTTP responses. This information disclosure can aid attackers in fingerprinting the environment and crafting targeted exploits. The issue affects all POST endpoints accepting JSON bodies. A fix is available in vLLM 0.26.0 that changes the error handling to avoid leaking such details.
