The Import and export users and customers plugin for WordPress is vulnerable to Privilege Escalation in all versions up to and including 2.0.8 via the `save_extra_user_profile_fields()` function. This is due to an incomplete blocklist that correctly restricts capability meta keys for the primary site (e.g., `wp_capabilities`, `wp_user_level`) but fails to block the equivalent meta keys for any other subsite in a WordPress Multisite network (e.g., `wp_2_capabilities`, `wp_2_user_level`), allowing these keys to pass the `in_array()` check and be written directly to user meta via `update_user_meta()`. This makes it possible for authenticated attackers, with Subscriber-level access and above, to escalate their privileges to Administrator on any subsite within the Multisite network by submitting a crafted profile update to `/wp-admin/profile.php`. Exploitation requires that an administrator has previously imported a CSV file containing multisite-prefixed capability column headers and has enabled the 'Show fields in profile?' option, which causes those keys to be stored in the `acui_columns` option and exposed as editable fields on the user profile page.
The Import and export users and customers WordPress plugin versions up to 2.0.8 contains a privilege escalation vulnerability in the save_extra_user_profile_fields() function due to incomplete blocklist validation. Authenticated subscribers can escalate privileges to administrator on any WordPress Multisite subsite by manipulating user meta keys like wp_2_capabilities.
تحتوي إضافة استيراد وتصدير المستخدمين والعملاء على ثغرة تصعيد امتيازات في دالة save_extra_user_profile_fields() حيث تفشل قائمة الحجب في منع مفاتيح meta الخاصة بمواقع فرعية متعددة مثل wp_2_capabilities و wp_2_user_level. يمكن للمستخدمين المصرح لهم بمستوى المشترك وما فوقه استغلال هذه الثغرة لتصعيد امتيازاتهم إلى مستوى المسؤول على أي موقع فرعي في شبكة WordPress Multisite.

Update the Import and export users and customers plugin to version 2.0.9 or later immediately. If immediate patching is not possible, disable the plugin and remove it from all WordPress installations. Review user accounts for unauthorized privilege escalation and audit access logs for suspicious profile updates to /wp-admin/profile.php.
قم بتحديث إضافة Import and export users and customers إلى الإصدار 2.0.9 أو أحدث فوراً. إذا لم يكن التحديث فوراً ممكناً، قم بتعطيل الإضافة وإزالتها من جميع تثبيتات WordPress. راجع حسابات المستخدمين للتحقق من تصعيد الامتيازات غير المصرح به وتدقيق سجلات الوصول للتحديثات المريبة.
