CVE-2026-35676 Details
Description
phpMyFAQ before 4.1.3 contains an unauthenticated password reset vulnerability in the user password update API endpoint that allows attackers to change account passwords without token validation. Attackers can enumerate valid username and email pairs and force immediate password changes by sending PUT requests to the /api/index.php/user/password/update endpoint, causing account disruption and invalidating legitimate user credentials.
A vulnerability exists in phpMyFAQ versions prior to 4.1.3, allowing unauthenticated users to reset passwords through the user password update API endpoint. This flaw enables attackers to change passwords without proper token validation. By sending PUT requests to the /api/index.php/user/password/update endpoint, attackers can disrupt accounts and invalidate legitimate user credentials. The vulnerability also allows for enumeration of valid username and email pairs, as the API response differs between valid and invalid combinations.
Users are advised to update to phpMyFAQ version 4.1.3 or later, where this vulnerability has been patched.
