CVE-2026-35671: phpMyFAQ: IDOR Account Takeover

May 20, 2026 (updated May 31, 2026)

An Insecure Direct Object Reference (IDOR) vulnerability in phpMyFAQ’s Admin API allows any authenticated administrator to change the password of any user account, including SuperAdmin accounts (userId=1), without authorization verification. An attacker with a low-privilege admin account can escalate privileges to full SuperAdmin control by simply changing the target user’s ID in the API request body.
