CVE-2025-3844: Peprodev Ultimate Profile Solutions

Critical severity, CVSS 9.8. EPSS: 0.6% chance of exploitation in the next 30 days.

The PeproDev Ultimate Profile Solutions plugin for WordPress is vulnerable to Authentication Bypass in versions 1.9.1 to 7.5.2. This is due to handel_ajax_req() function not having proper restrictions on the change_user_meta functionality that makes it possible to set a OTP code and subsequently log in with that OTP code. This makes it possible for unauthenticated attackers to login as other users on the site, including administrators.
