CVE-2025-11750Network attack vector

Account enumeration via distinct authentication errors

Published Oct 22, 2025 · Updated Oct 22, 2025

User enumeration in LangGenius Dify 1.6.0 allows remote attackers to identify registered accounts through authentication responses. Login and registration return an account-not-found error for unknown identities but a different error when an existing identity is paired with an incorrect password. No authentication is required to compare the responses, exposing valid usernames or email addresses for targeted credential attacks.
