CVE-2026-45010 Details
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 vulnerability in phpMyFAQ versions prior to 4.1.2 allows unauthenticated attackers to bypass two-factor authentication by brute-forcing users' TOTP codes. This issue arises from the /admin/check endpoint, which accepts arbitrary user-id parameters without session verification or rate limiting. Attackers can exploit this flaw by sending POST requests with sequential token values, gaining full administrative access on the platform.
Users are advised to update phpMyFAQ to version 4.1.2 or later, where this vulnerability has been patched.
