CVE-2026-45010 is a critical-severity vulnerability rated 9.3/10 on the CVSS scale. 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.. EPSS estimates a 0.34% chance of exploitation in the next 30 days.
