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.","published_at":"2026-04-11T01:25:00.447000Z","last_modified_at":null,"cvss_v3_score":5.0,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-918"],"nvd_references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/9cd2b3fd-1bca-4611-9753-ccb57b0e36a4?source=cve","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","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://github.com/AyeCode/userswp/commit/ca0c81b9c76a26c5ac78a8f3604cf9122a7a4aa1"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:30:46.591291Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"C","value_label":"Changed"},{"metric":"C","name":"Confidentiality","value":"L","value_label":"Low"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"stiofansisland","vendor_name":"stiofansisland","product_slug":"userswp-front-end-login-form-user-registration-user-profile-members-directory-plugin-for-wp","product_name":"UsersWP – Front-end login form, User Registration, User Profile & Members Directory plugin for WP","version_start":"0","version_start_inclusive":true,"version_end":"1.2.58","version_end_inclusive":true,"cpe23_uri":"cve5:stiofansisland:userswp-front-end-login-form-user-registration-user-profile-members-directory-plugin-for-wp:0:1.2.58"}],"exploit_refs":[],"news":[],"references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/9cd2b3fd-1bca-4611-9753-ccb57b0e36a4?source=cve","source_type":"MISC","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/userswp/trunk/includes/class-forms.php#L198","source_type":"MISC","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/userswp/trunk/includes/helpers/misc.php#L136","source_type":"MISC","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/userswp/tags/1.2.55/includes/class-forms.php#L198","source_type":"MISC","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/userswp/tags/1.2.55/includes/helpers/misc.php#L136","source_type":"MISC","tags":[]},{"url":"https://github.com/AyeCode/userswp/commit/ca0c81b9c76a26c5ac78a8f3604cf9122a7a4aa1","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-04-11T01:25:00.447000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:55:22.518073Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:55:22.518073Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:55:22.518073Z","label":"CVSS score revised","source":"cvelistv5"}]}
