This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The payload is stored via the WordPress core REST endpoint POST /wp-json/wp/v2/users/me, which bypasses the plugin's own wpum_sanitize_text sanitizer applied on its front-end account form, making the save-time sanitization ineffective as a mitigation.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":6.4,"severity":"medium","source":"CNA: Wordfence","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1793957892531,"publishedAt":1793957892531,"references":[{"source":"CNA: Wordfence","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/3e9da4a7-89ba-426c-943a-e7bc79a04d7c?source=cve"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/wp-user-manager/tags/2.10.2/includes/fields/types/class-wpum-field-dropdown.php#L60"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/wp-user-manager/tags/2.10.2/includes/fields/class-wpum-field.php#L627"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/wp-user-manager/tags/2.10.2/templates/profiles/about.php#L51"},{"source":"CNA: Wordfence","tags":[],"url":"https://plugins.trac.wordpress.org/browser/wp-user-manager/tags/2.10.2/includes/fields/wpum-fields-functions.php#L578"},{"source":"CNA: Wordfence","tags":[],"url":"https://downloads.wordpress.org/plugin/wp-user-manager.2.10.3.zip"}],"remediation":[],"revision":"7060d894b2f03bffe7208d8447913d7266e07743a8e4f7c737bea31f652374c3","sources":[{"modifiedAt":1793957892531,"name":"CNA: Wordfence","retrievedAt":1793959708754,"url":"https://www.cve.org/CVERecord?id=CVE-2026-120550"}],"ssvc":null,"status":"published","title":"WP User Manager <= 2.10.2 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'display_name' User Meta","updatedAt":1793959708754}
