Executive Summary

The Disable Users WordPress plugin through version 1.0.5 fails to enforce account-disabling controls on all authentication paths. This means an administrator may disable a user account, but the disabled user can still authenticate via XML-RPC or Application Passwords and retain full privileges.

Detection Guidance

Check if the Disable Users WordPress plugin version 1.0.5 or lower is installed. Inspect authentication logs for unauthorized access attempts via XML-RPC or Application Passwords. Verify if disabled user accounts retain full privileges.

Impact Analysis

This vulnerability allows disabled user accounts to bypass restrictions and access the WordPress site with full privileges. Attackers could exploit this to regain unauthorized access even after being disabled by an administrator.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating GDPR's data protection principles and HIPAA's access control requirements. Unrestricted access via disabled accounts may result in data breaches or unauthorized modifications, undermining compliance with these regulations.

Mitigation Strategies

Update the Disable Users plugin to the latest version immediately. Disable XML-RPC if not required. Review and revoke Application Passwords for disabled accounts. Monitor user activity for suspicious logins.
