AnalysisAIv1 – Jul 28, 2026

Unauthenticated arbitrary user session termination (force-logout) in the Masteriyo LMS WordPress plugin before version 2.3.1 allows remote attackers to log out any site user, including administrators, via an insecure AJAX action. Publicly available exploit code exists, but no active exploitation has been confirmed by CISA KEV. The high CVSS score from NVD likely overstates impact, as the flaw only disrupts sessions without exposing data.
