AI Engine <= 3.6.5 - Cross-Site Request Forgery to Privilege Escalation via REQUEST_URI Substring Match
Affected versions: *-3.6.5
Vulnerability type: CWE-352 Cross-Site Request Forgery (CSRF)
Affected software, patched versions and attribution
The AI Engine – The Chatbot, AI Framework & MCP for WordPress plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 3.6.5 This is due to missing or incorrect nonce validation on the reauth_for_authorize function. This makes it possible for unauthenticated attackers to create new administrator accounts with attacker-supplied credentials via a CSRF-based REST authentication bypass, granted they can trick a site administrator into performing an action such as clicking on a link. This bypass can be combined with WordPress's ?_method=POST method-override support to convert a top-navigation GET request into an authenticated POST to the REST users endpoint, requiring no existing account on the attacker's part.
