Detailsinfo

A vulnerability, which was classified as problematic, has been found in projectzealous01 PZ Frontend Manager Plugin up to 1.0.6 on WordPress. Affected by this issue is the function pzfm_user_request_action_callback of the component AJAX Endpoint. The manipulation of the argument dataType with an unknown input leads to a authorization vulnerability. Using CWE to declare the problem leads to CWE-862. The product does not perform an authorization check when an actor attempts to access a resource or perform an action. Impacted is integrity, and availability. CVE summarizes:

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.

The weakness was shared by Youcef Hamdani. The advisory is shared for download at wordfence.com. This vulnerability is handled as CVE-2026-3477 since 03/03/2026. The exploitation is known to be easy.
