Description

The WP Travel Pro plugin for WordPress is vulnerable to arbitrary user deletion via the /wp-json/wp-travel/v1/travel-guide/{user_id} REST API endpoint in all versions up to, and including, 10.6.0. This is due to the check_permission() callback unconditionally returning true and the Database::delete() method passing the user ID directly to wp_delete_user() without any role validation. This makes it possible for unauthenticated attackers to delete arbitrary user accounts, including those of administrators.
