CVE-2026-4106: The Authorization Gap
CVE-2026-4106 involves missing authorization checks in AJAX handlers. The plugin fails to verify user capabilities before processing requests. This means lower-privilege users can run administrative functions. They can access features reserved for site administrators.

Affected Versions

Monitor your site for unauthorized changes. Use a security plugin to detect suspicious activity. Enable logging for AJAX requests if possible. This helps you spot exploitation attempts early.
