CVE-2026-45010: Improper Restriction of Excessive Authentication Attempts in thorsten phpmyfaq
phpMyFAQ before 4.1.2 contains an improper restriction of excessive authentication attempts vulnerability in the /admin/check endpoint, which accepts arbitrary user-id parameters without session binding or rate limiting. Unauthenticated attackers can brute-force any user's six-digit TOTP code by submitting POST requests with sequential token values, bypassing two-factor authentication to gain full administrative access.
AI Analysis
Technical Summary
CVE-2026-45010 describes an improper restriction of excessive authentication attempts vulnerability in phpMyFAQ prior to version 4.1.2. The affected endpoint (/admin/check) accepts arbitrary user-id parameters and lacks session binding and rate limiting controls. This allows unauthenticated attackers to brute-force any user's six-digit TOTP code by submitting sequential token values via POST requests. Successful exploitation bypasses two-factor authentication, granting full administrative privileges.
Potential Impact
Exploitation results in unauthorized full administrative access to phpMyFAQ instances, compromising confidentiality and integrity of the system. The vulnerability does not affect availability. The CVSS score of 9.1 reflects the critical nature of this authentication bypass.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the /admin/check endpoint through network controls or web application firewalls to limit brute-force attempts. Monitor for unusual authentication activity targeting this endpoint.
