CVE-2026-14526

critical

Description

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. This vulnerability is exploitable by unauthenticated attackers on any site where the [aiwu-form] shortcode or public chatbot is rendered on a frontend page, as the waic-nonce value is emitted into publicly accessible JavaScript (WAIC_DATA.waicNonce) on those pages, rendering the nonce check a non-functional authorization barrier.
