phpMyFAQ versions before 4.1.8 contain an authentication bypass vulnerability in the user control panel API endpoint that allows authenticated attackers to change account passwords without verifying the current password. Attackers with session access can submit a PUT request to the user data update endpoint with only a CSRF token to silently change any user's password, including administrators, causing irreversible account takeover and victim lockout.
AnalysisAI
Authenticated account takeover in phpMyFAQ before 4.1.8 allows any authenticated user-including low-privileged accounts-to silently reset the password of any other account, including administrators, by submitting a crafted PUT request to the user data update API endpoint with only a CSRF token and no current-password verification. Successful exploitation locks the victim out of their account irreversibly and grants the attacker full control of that account, enabling vertical privilege escalation from a low-privilege user to administrator. …
