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.","publishedAt":"2026-10-10T06:40:09.032Z","updatedAt":"2026-10-11T12:23:56.023Z","severity":{"score":6.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["wedevs User Frontend – Membership, User Registration, User Profile, User Directory & Content Restriction with Frontend Post Submission"],"affected":[{"vendor":"wedevs","product":"User Frontend – Membership, User Registration, User Profile, User Directory & Content Restriction with Frontend Post Submission","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.3.12","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/12f1cbc1-42c1-4ace-88ec-8aa981367c85?source=cve","https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.12/includes/Admin/List_Table_Transactions.php#L204","https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.12/wpuf-functions.php#L2498","https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.12/includes/Frontend/Payment.php#L566","https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.12/Lib/Gateway/Bank.php#L102","https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.12/includes/Frontend/Payment.php#L503","https://plugins.trac.wordpress.org/changeset/3722911/wp-user-frontend/trunk/includes/Admin/List_Table_Transactions.php"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:13:43.249Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/96xxx/CVE-2026-96574.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-96574","state":"PUBLISHED","datePublished":"2026-10-10T06:40:09.032Z","dateUpdated":"2026-10-11T12:23:56.023Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-09-23T13:27:27.250Z"},"containers":{"cna":{"title":"User Frontend <= 4.3.12 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'wpuf_payment_method' Parameter","descriptions":[{"lang":"en","value":"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.
