Executive Summary

The Vayu X WordPress theme before version 1.0.6 has a flaw where it does not check user permissions for an AJAX action. This allows any logged-in user, even those with minimal roles like subscribers, to install and activate plugins from the WordPress.org repository. The theme also exposes the security token (nonce) needed for this action to all logged-in users.

Detection Guidance

Check the installed version of the Vayu X WordPress theme. If it is below 1.0.6, the system is vulnerable. Use WordPress admin dashboard or run a command like 'wp theme list' in the WordPress directory to verify the version.

Impact Analysis

An attacker with access to a low-privilege account could exploit this to install malicious or unwanted plugins on your WordPress site. This could lead to further compromise of your site, data theft, or unauthorized changes. Even trusted users with basic accounts could accidentally or intentionally misuse this access.

Compliance Impact

This vulnerability could lead to unauthorized plugin installations, potentially violating compliance requirements for data protection (GDPR) or healthcare data (HIPAA) by allowing access to sensitive data or systems. It undermines access control measures required by these standards.

Mitigation Strategies

Update the Vayu X theme to version 1.0.6 or later immediately. Remove unnecessary user roles like subscribers if possible. Monitor for unauthorized plugin installations.
