What is CVE-2026-13332?

The Masteriyo LMS plugin for WordPress prior to version 2.3.1 contains a vulnerability that permits unauthenticated attackers to exploit an AJAX action related to user session management. This flawed implementation allows unauthorized users to clear active sessions for any registered user, including administrators, effectively removing their access without consent. This vulnerability poses a significant risk as it undermines the site's ability to maintain user sessions securely.

Affected Version(s)

Masteriyo LMS 0 < 2.3.1
