CVE-2025-54868Public exploitNetwork attack vector

Unauthenticated chat disclosure via unrestricted search endpoint

Published Aug 5, 2025 · Updated Aug 5, 2025

Improper authorization in LibreChat 0.0.6 through 0.7.7-rc1 allows remote attackers to read arbitrary users' chats over the network. The GET /api/search/test handler in api/server/routes/search.js passes q to Message.meiliSearch and returns matching hits without restricting them to the requesting user. No privileges or user interaction are required; omitting q returns arbitrary stored chats, and the reported consequence is limited to disclosure.
