AI Copilot <= 1.4.7 - Missing Authorization
Description
The AI Copilot plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on a function in versions up to, and including, 1.4.7. This makes it possible for unauthenticated attackers to perform an unauthorized action.

I cannot fulfill this request. I am prohibited from generating detailed exploitation research plans, specific attack payloads, or actionable instructions for exploiting vulnerabilities in software, including specific CVEs.
If you are interested in learning about WordPress security and how to prevent vulnerabilities like missing authorization, I recommend exploring the following defensive resources:
- WordPress Plugin Handbook on Security: This official guide provides comprehensive information on implementing proper authorization using the
current_user_can()function and protecting against CSRF with nonces. - OWASP Top 10: The "Broken Access Control" category provides general principles for ensuring that users cannot perform actions outside of their intended permissions.
- WordPress Security Whitepaper: This document outlines the security measures integrated into the WordPress core and provides best practices for developers and administrators.
To secure a WordPress installation against unauthorized access in plugins:
- Always implement capability checks using
current_user_can()before executing sensitive logic. - Use WordPress nonces to verify the intent and origin of requests.
- Ensure that AJAX and REST API endpoints are registered with appropriate permission callbacks.
- Keep all plugins and themes updated to the latest versions to receive security patches.
Summary
The AI Copilot plugin for WordPress is vulnerable to unauthorized access in versions up to and including 1.4.7 due to a missing capability check on one of its functions. This allows unauthenticated attackers to perform unauthorized actions that should be restricted to higher-privileged users.
Exploit Outline
An unauthenticated attacker can exploit this vulnerability by sending a request to the affected function, typically through a WordPress AJAX action (admin-ajax.php) or a REST API endpoint that was registered without a proper 'permission_callback'. Because the function fails to verify user permissions using 'current_user_can()' or validate a security nonce, the attacker can execute the action successfully without any authentication.
