- Summary
- LibreChat's IDOR in SSE Stream Subscription Allows Reading Other Users' Chats
- Details
-
LibreChat is a ChatGPT clone with additional features. In versions 0.8.2-rc2 through 0.8.2-rc3, the SSE streaming endpoint
/api/agents/chat/stream/:streamIddoes not verify that the requesting user owns the stream. Any authenticated user who obtains or guesses a valid stream ID can subscribe and read another user's real-time chat content, including messages, AI responses, and tool invocations. Version 0.8.2 patches the issue. - Database specific
