What is CVE-2026-45010?

The phpMyFAQ software before version 4.1.2 is vulnerable to a serious flaw that allows unauthenticated attackers to exploit the /admin/check endpoint. This vulnerability permits the submission of arbitrary user-id parameters, which, combined with the absence of session binding and rate limiting, enables attackers to initiate brute-force attacks against any user's six-digit TOTP code. Successfully bypassing two-factor authentication can grant the attacker full administrative access to the phpMyFAQ system.
