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.
Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
