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."}],"title":"UsersWP <= 1.2.58 - Authenticated (Subscriber+) Server-Side Request Forgery via 'uwp_crop' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/9cd2b3fd-1bca-4611-9753-ccb57b0e36a4?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/userswp/trunk/includes/class-forms.php#L198"},{"url":"https://plugins.trac.wordpress.org/browser/userswp/trunk/includes/helpers/misc.php#L136"},{"url":"https://plugins.trac.wordpress.org/browser/userswp/tags/1.2.55/includes/class-forms.php#L198"},{"url":"https://plugins.trac.wordpress.org/browser/userswp/tags/1.2.55/includes/helpers/misc.php#L136"},{"url":"https://github.com/AyeCode/userswp/commit/ca0c81b9c76a26c5ac78a8f3604cf9122a7a4aa1"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-918 Server-Side Request Forgery (SSRF)","cweId":"CWE-918","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N","baseScore":5,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Mariusz Maik"}],"timeline":[{"time":"2026-03-27T11:08:48.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-04-10T12:14:59.000Z","lang":"en","value":"Disclosed"}]}}}
