Detection Guidance

This vulnerability involves broken access control in the WordPress Restrict Content Plugin versions up to and including 3.2.22, allowing unauthorized privilege escalation due to missing authorization checks.

Detection typically involves verifying the plugin version installed on your WordPress site to see if it is vulnerable (version ≤ 3.2.22).

You can check the plugin version by running commands on your server such as:

• Using WP-CLI: wp plugin list | grep restrict-content
• Manually checking the plugin version in the plugin's main PHP file, e.g., cat wp-content/plugins/restrict-content/restrict-content.php | grep 'Version'

Additionally, monitoring for unusual privilege escalation attempts or unauthorized actions in your WordPress logs may help detect exploitation attempts, but no specific detection commands or signatures are provided.
