The School Management System for Wordpress plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the 'mj_smgt_remove_feetype' and 'mj_smgt_remove_category_new' AJAX actions in all versions up to, and including, 93.0.0. This makes it possible for unauthenticated attackers to delete arbitrary posts.
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
