The WOLF – WordPress Posts Bulk Editor and Manager Professional plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0.8.1. This is due to missing or incorrect nonce validation on the wpbe_create_new_term, wpbe_update_tax_term, and wpbe_delete_tax_term functions. This makes it possible for unauthenticated attackers to create, modify and delete taxonomy terms via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. Furthermore, the functions wpbe_save_options, wpbe_bulk_delete_posts_count, wpbe_bulk_delete_posts, and wpbe_save_meta are vulnerable to Cross-Site Request Forgery allowing for plugin options update, post count deletion, post deletion and modification of post metadata via forged request.
The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
