The UsersWP – Front-end login form, User Registration, User Profile & Members Directory plugin for WP plugin for WordPress is vulnerable to blind Server-Side Request Forgery in all versions up to, and including, 1.2.58. This is due to insufficient URL origin validation in the process_image_crop() method when processing avatar/banner image crop operations. The function accepts a user-controlled URL via the uwp_crop POST parameter and only validates it using esc_url() for sanitization and wp_check_filetype() for extension verification, without enforcing that the URL references a local uploads file. The URL is then passed to uwp_resizeThumbnailImage() which uses it in PHP image processing functions (getimagesize(), imagecreatefrom*()) that support URL wrappers and perform outbound HTTP requests. This makes it possible for authenticated attackers with subscriber-level access and above to coerce the WordPress server into making arbitrary HTTP requests to attacker-controlled or internal network destinations, enabling internal network scanning and potential access to sensitive services.
The UsersWP WordPress plugin versions up to 1.2.58 contain a blind Server-Side Request Forgery (SSRF) vulnerability in image crop functionality that allows authenticated attackers to make arbitrary outbound HTTP requests. The vulnerability exists due to insufficient URL validation in the process_image_crop() method, which fails to enforce that URLs reference only local upload files.
ثغرة SSRF العمياء في إضافة UsersWP تسمح للمهاجمين المصرحين على مستوى المشترك وما فوق بإجراء طلبات HTTP عشوائية. تنشأ الثغرة من عدم كفاية التحقق من أصل URL في دالة process_image_crop() التي تفشل في فرض أن تشير عناوين URL فقط إلى ملفات التحميل المحلية.
UsersWP WordPress plugin versions up to 1.2.58 contain a blind SSRF vulnerability in image crop functionality allowing authenticated attackers to make arbitrary outbound HTTP requests. The vulnerability stems from insufficient URL origin validation in the process_image_crop() method that fails to restrict URLs to local uploads.
Update the UsersWP plugin to version 1.2.59 or later immediately. Implement strict URL validation to ensure image crop operations only reference local WordPress upload directories. Restrict outbound HTTP requests from image processing functions and apply network segmentation to limit internal resource access from web servers.
