In langgenius/dify-web version 1.6.0, the authentication mechanism reveals the existence of user accounts by returning different error messages for non-existent and existing accounts. Specifically, when a login or registration attempt is made with a non-existent username or email, the system responds with a message such as "account not found." Conversely, when the username or email exists but the password is incorrect, a different error message is returned. This discrepancy allows an attacker to enumerate valid user accounts by analyzing the error responses, potentially facilitating targeted social engineering, brute force, or credential stuffing attacks.

CVE-2025-11750 [MEDIUM] Dify - User Enumeration via "Account not found" Message
Dify - User Enumeration via "Account not found" Message
A user enumeration vulnerability exists in langgenius/dify, where the login API leaks information about whether a user account exists or not. When an invalid/non-existent email is used during login, the API returns a distinct error message such as "account_not_found" or "Account not found.", allowing attackers to identify valid accounts.
