Detailsinfo

A vulnerability, which was classified as critical, was found in wupsales AI Copilot Plugin up to 1.5.6. Affected is the function wp_create_user of the component Shortcode. The manipulation of the argument waic-nonce with an unknown input leads to a authorization vulnerability. CWE is classifying the issue as CWE-639. The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. This is going to have an impact on integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at wordfence.com. This vulnerability is traded as CVE-2026-14526 since 07/02/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are known technical details, but no exploit is available.
