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 PZ Frontend Manager WordPress plugin versions up to 1.0.6 contain a missing authorization vulnerability in the pzfm_user_request_action_callback() function that allows authenticated users to delete arbitrary WordPress users including administrators. The vulnerability lacks both capability checks and nonce verification, enabling privilege escalation attacks through AJAX requests.
ثغرة نقص التفويض في إضافة PZ Frontend Manager لـ WordPress تسمح للمستخدمين المصرح لهم بمستوى المشترك فما فوق بحذف مستخدمي WordPress التعسفيين بما في ذلك المسؤولين. تفتقر الدالة pzfm_user_request_action_callback() إلى فحوصات القدرات والتحقق من nonce، مما يمكّن هجمات تصعيد الامتيازات من خلال طلبات AJAX.
The PZ Frontend Manager WordPress plugin versions up to 1.0.6 contain a missing authorization vulnerability in the pzfm_user_request_action_callback() function that allows authenticated users to delete arbitrary WordPress users including administrators. The vulnerability lacks both capability checks and nonce verification, enabling privilege escalation attacks through AJAX requests.
Update the PZ Frontend Manager plugin to version 1.0.7 or later immediately. Implement capability checks using current_user_can() to verify administrator privileges before user deletion operations. Add nonce verification using wp_verify_nonce() for all AJAX callbacks. Restrict the pzfm_user_request_action_callback() function to administrator-only access. Audit user deletion logs to identify any unauthorized deletions.
قم بتحديث إضافة PZ Frontend Manager إلى الإصدار 1.0.7 أو أحدث فوراً. قم بتنفيذ فحوصات القدرات باستخدام current_user_can() للتحقق من امتيازات المسؤول قبل عمليات حذف المستخدمين. أضف التحقق من nonce باستخدام wp_verify_nonce() لجميع استدعاءات AJAX. قيد وظيفة pzfm_user_request_action_callback() للوصول الحصري للمسؤولين. قم بمراجعة سجلات حذف المستخدمين للتعرف على أي حذف غير مصرح به.
