CyberRota Analysis
AI-GeneratedThe YITH WooCommerce Waitlist Premium plugin for WordPress versions up to 3.35.0 is vulnerable to privilege escalation due to inadequate capability checks and nonce verification in the add_user_in_waiting_list() function. This flaw allows authenticated users with Subscriber-level access and above to create new user accounts with administrator privileges, potentially compromising the entire site. WordPress site administrators using this plugin should prioritize immediate updates to mitigate the risk of unauthorized access.
Original NVD Description
The YITH WooCommerce Waitlist Premium plugin for WordPress is vulnerable to Privilege Escalation in versions up to, and including, 3.35.0. This is due to the add_user_in_waiting_list() function registered on the wp_ajax_yith_wcwtl_add_user action being missing both a capability check and a nonce verification, and using parse_str() + extract() to import attacker-controlled variables from $_POST['params'] that are then passed to wp_create_user() and $user->set_role(). This makes it possible for authenticated attackers, with Subscriber-level access and above, to elevate their privileges to that of an administrator by creating a new user account and assigning it the administrator role.
