Detection Guidance

This vulnerability allows unauthenticated attackers to register as administrator users due to improper role restrictions in the doctreat_process_registration() function of the Doctreat Core plugin for WordPress.

To detect if your system is vulnerable, you can check the installed version of the Doctreat plugin. Versions up to and including 1.6.8 are vulnerable, while version 1.7.0 and later include the fix.

You can detect the plugin version by running the following command in the WordPress installation directory:

• grep -i 'Version' wp-content/plugins/doctreat-core/readme.txt

Alternatively, you can check the plugin version via WP-CLI:

• wp plugin get doctreat-core --field=version

To detect if unauthorized administrator accounts have been created, you can list all users with administrator roles using WP-CLI:

• wp user list --role=administrator

Review the list for any suspicious or unknown administrator accounts that may have been created without authorization.
