CVE-2026-14526

Status: DeferredCritical (9.8)—

The AI Copilot – Content Generator plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.5.6. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to create a new administrator-level user account and achieve full site takeover by saving and executing a malicious workflow containing a wp_create_user action node specifying role=administrator.
