Duplicate Advisory: phpMyFAQ enables unauthenticated 2FA brute-force attack via /admin/check acceptance of arbitrary user-id
GitHub lists this reviewed advisory for thorsten/phpmyfaq, phpmyfaq/phpmyfaq. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.

thorsten/phpmyfaq
source listed< 4.1.2
### Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-9pq7-mfwh-xx2j. This link is maintained to preserve external references. ### Original Description 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.

A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
