Executive Summary

This vulnerability affects the RestrictMate WordPress plugin before version 1.3.0. It allows unauthenticated attackers to create a new administrator account by exploiting improper role restrictions during registration. This leads to a full site takeover as attackers gain administrator privileges.

Detection Guidance

Check if the RestrictMate plugin is installed and verify its version. If the version is below 1.3.0, the system is vulnerable. Use WordPress admin panel or run commands like 'wp plugin list' in the WordPress directory to check the plugin version.

Impact Analysis

An attacker could exploit this to gain full control of your WordPress site by creating an admin account without authentication. This could result in unauthorized changes, data theft, or complete site compromise.

Compliance Impact

This vulnerability could lead to unauthorized access and data breaches, violating GDPR and HIPAA requirements for data protection and access control. Compliance may be compromised due to potential exposure of sensitive user or patient data.

Mitigation Strategies

Update the RestrictMate plugin to version 1.3.0 or later immediately. If updating is not possible, consider temporarily disabling the plugin until an update is applied to prevent exploitation.
