CVE-2026-79483Public exploitNetwork attack vector

Unauthorized chat-title access via NoSQL operator injection

Published Aug 31, 2026 · Updated Sep 1, 2026

NoSQL injection in FastGPT Community Edition 4.10.0 through 4.14.0 allows remote attackers to read all users' chat history titles. The endpoint's authOutLinkInit() path accepts operator-bearing JSON without runtime type validation, so MongoDB evaluates attacker-supplied selection logic during the outLink permission check. No account or user interaction is required; the disclosed impact is limited to chat history titles, with no reported access to message contents or modification.
