CVE-2026-14526
CriticalCVSS 9.8Summary
The AI Copilot – Content Generator plugin for WordPress up to version 1.5.6 has an authorization bypass vulnerability. Unauthenticated attackers can create an administrator account and take over the site by saving and executing a malicious workflow with wp_create_user. This is possible because the nonce is exposed in public JavaScript.
Risk Assessment
The risk is critical as the attack requires no authentication and can lead to full site takeover, potentially resulting in data theft, defacement, or further attacks from the compromised server.
Recommendation
Immediately update the plugin to the latest version if available, and temporarily disable the [aiwu-form] shortcode and public chatbot if not essential, until a patch is applied.
Original NVD description (English source)
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.
