{"cve":"CVE-2026-4979","nvd":{"published":"2026-04-11T02:16:02.463","modified":"2026-06-17T10:57:32.470","status":"Deferred","description":"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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N","score":5.0},"cwes":["CWE-918"],"references":["https://github.com/AyeCode/userswp/commit/ca0c81b9c76a26c5ac78a8f3604cf9122a7a4aa1","https://plugins.trac.wordpress.org/browser/userswp/tags/1.2.55/includes/class-forms.php#L198","https://plugins.trac.wordpress.org/browser/userswp/tags/1.2.55/includes/helpers/misc.php#L136","https://plugins.trac.wordpress.org/browser/userswp/trunk/includes/class-forms.php#L198","https://plugins.trac.wordpress.org/browser/userswp/trunk/includes/helpers/misc.php#L136"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:28:59.047572785+00:00"},"epss":{"cve":"CVE-2026-4979","score":0.00356,"percentile":0.29363,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
