{"id":"CVE-2026-96574","published":"2026-10-10T07:16:42.627","lastModified":"2026-10-13T13:30:21.620","description":"The User Frontend – Membership, User Registration, User Profile, User Directory & Content Restriction with Frontend Post Submission plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wpuf_payment_method' parameter in all versions up to, and including, 4.3.12 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 bypass technique involves appending a valid gateway keyword such as 'bank' to the HTML payload, causing sanitize_text_field() to yield only the keyword for routing purposes while the full malicious raw value is stored and later rendered unescaped.","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/wp-user-frontend/tags/4.3.12/Lib/Gateway/Bank.php#L102","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.12/includes/Admin/List_Table_Transactions.php#L204","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.12/includes/Frontend/Payment.php#L503","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.12/includes/Frontend/Payment.php#L566","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.12/wpuf-functions.php#L2498","tags":[]},{"url":"https://plugins.trac.wordpress.org/changeset/3722911/wp-user-frontend/trunk/includes/Admin/List_Table_Transactions.php","tags":[]},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/12f1cbc1-42c1-4ace-88ec-8aa981367c85?source=cve","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
