GHSA-9G7R-H55W-795G

Vulnerability from github – Published: 2025-09-11 03:30 – Updated: 2025-09-11 03:30

Details

In version 0.7.8 of danny-avila/librechat, improper authorization controls in the conversation sharing feature allow unauthorized access to other users' conversations if the conversation ID is known. Although UUIDv4 conversation IDs are generated server-side and are difficult to brute force, they can be obtained from less-protected sources such as server-side access logs, browser history, or screenshots. The vulnerability permits a logged-in user to gain read-only access to another user's conversations by exploiting the /api/share/conversationID endpoint, which lacks authorization checks. This issue is resolved in version v0.7.9-rc1.

Severity ?

4.2 (Medium)
