{"id":"CVE-2026-120550","published":"2026-11-06T10:16:37.047","lastModified":"2026-11-06T15:17:13.433","description":"The WP User Manager – Registration Form, Login Form, User Profile Builder & Member Directory plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'name (REST users endpoint) -> wp_users.display_name' parameter in all versions up to, and including, 2.10.2 due to insufficient input sanitization and output escaping. 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.","cvssScore":6.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://downloads.wordpress.org/plugin/wp-user-manager.2.10.3.zip","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wp-user-manager/tags/2.10.2/includes/fields/class-wpum-field.php#L627","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wp-user-manager/tags/2.10.2/includes/fields/types/class-wpum-field-dropdown.php#L60","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wp-user-manager/tags/2.10.2/includes/fields/wpum-fields-functions.php#L578","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wp-user-manager/tags/2.10.2/templates/profiles/about.php#L51","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/3e9da4a7-89ba-426c-943a-e7bc79a04d7c?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
