WordPress AI Copilot Plugin Allows Unauthenticated Admin Account Creation

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.

Casky was already ahead

This CVE exploits attack patterns that Casky's 224matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

The AI Copilot – Content Generator plugin for WordPress contains a critical authorization bypass vulnerability (CVE-2026-14526, CVSS 9.8) affecting all versions through 1.5.6. The plugin fails to properly verify user permissions before executing workflow actions, allowing unauthenticated attackers to create administrator-level accounts by crafting malicious workflows with wp_create_user action nodes. This vulnerability represents a complete site takeover risk for any WordPress installation running the affected plugin, impacting content creators, agencies, and enterprises relying on this AI-powered content generation tool. The attack requires no prior authentication, making it trivially exploitable and an immediate priority for remediation.

Casky's 224 mapped skills detect the attack patterns underlying this vulnerability by analyzing TA0004 (Privilege Escalation) techniques through Claude's extended reasoning capabilities. Practitioners using Casky would identify suspicious patterns including: unauthorized administrative account creation events in WordPress user tables, unexpected workflow execution without proper permission checks, API calls to wp_create_user from unauthenticated sources, and privilege escalation indicators in audit logs. The platform's skill coverage would flag the absence of authorization validation checks in plugin code, detect role parameter manipulation in workflow payloads, and surface lateral movement risks once admin access is established. Security teams would see detailed findings linking the authorization bypass mechanism (CWE-269) to specific exploitation chains, enabling faster threat hunting and incident response.
