Update, patch or deactivate.

Update PZ Frontend Manager to a release after 1.0.6, or disable and remove it until a fixed version is available.

Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.

Technical description

The PZ Frontend Manager plugin for WordPress is vulnerable to Missing Authorization in all versions up to and including 1.0.6. The pzfm_user_request_action_callback() function, registered via the wp_ajax_pzfm_user_request_action action hook, lacks both capability checks and nonce verification. This function handles user activation, deactivation, and deletion operations. When the 'dataType' parameter is set to 'delete', the function calls wp_delete_user() on all provided user IDs without verifying that the current user has the appropriate permissions. Notably, the similar pzfm_remove_item_callback() function does check pzfm_can_delete_user() before performing deletions, indicating this was an oversight. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary WordPress users (including administrators) by sending a crafted request to the AJAX endpoint.
