Summary
The Abandoned Contact Form 7 plugin for WordPress is vulnerable to unauthorized arbitrary post deletion in versions up to, and including, 2.2. This is due to a missing capability check and missing nonce validation in the action__remove_abandoned() function, which is registered to both the wp_ajax_remove_abandoned and wp_ajax_nopriv_remove_abandoned hooks. The handler takes a user-supplied recover_id parameter from $_POST and passes it directly to wp_delete_post() with the force-delete flag set to true, without verifying that the ID belongs to the plugin's own cf7af_data post type. This makes it possible for unauthenticated attackers to permanently delete arbitrary posts, pages, or other content on the affected site by sending a single admin-ajax.
