What to do
AI-suggested
Until a fix is available, restrict access to the affected endpoint where possible and monitor for suspicious requests attempting NoSQL injection patterns. Avoid exposing the vulnerable API publicly if feasible.
Description
FastGPT Community Edition 4.10.0 through 4.14.0 are vulnerable to a NoSQL injection in the POST /api/core/chat/getHistories endpoint. An unauthenticated attacker can inject malicious NoSQL operators via crafted JSON payloads to bypass authorization checks, resulting in unauthorized access to chat history titles of all users across the platform.
