CVE-2026-14526: Critical WordPress AI Copilot Flaw Found

What This Means

CVE ID: CVE-2026-14526
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.
CVSS 3.1 score: 9.8 (CRITICAL), vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
