{"id":"CVE-2026-107748","published":"2026-10-16T06:17:05.990","lastModified":"2026-10-16T15:17:05.440","description":"The User Profile Builder – Beautiful User Registration Forms, User Profiles & User Role Editor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'display_name' parameter in all versions up to, and including, 4.0.3 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 persists in wp_comments.comment_author independently of the user account, so removing or changing the attacker's display name after the comment is posted does not neutralize the stored script.","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://plugins.trac.wordpress.org/browser/profile-builder/tags/4.0.3/features/functions.php#L582","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/profile-builder/tags/4.0.3/features/functions.php#L585","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/profile-builder/tags/4.0.3/features/functions.php#L593","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/profile-builder/tags/4.0.3/front-end/default-fields/display-name/display-name.php#L81","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset/3741133/profile-builder","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset/3741133/profile-builder/trunk/features/functions.php","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/2f466add-992b-46c7-a1cc-5c05d59f4bdf?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
