CVE-2025-11750
User Enumeration via Distinct Error Messages in langgenius/dify-web
Description

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.

The Common Vulnerability Scoring System is a standardized framework for assessing the severity of vulnerabilities in software and systems. We collect and displays CVSS scores from various sources for each CVE.
Score Version Severity Vector Exploitability Score Impact Score Source
CVSS 3.0 MEDIUM [email protected]
Solution
Standardize authentication error messages to prevent account enumeration.
  • Implement uniform error messages for all authentication failures.
  • Avoid disclosing account existence in error responses.
  • Consider rate limiting and account lockout mechanisms.
