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.","state":0,"publishedAt":"2026-10-10T06:40:09.032+00:00","modifiedAt":"2026-10-11T12:23:56.023+00:00","affected":[{"ecosystem":"Vendor product","name":"User Frontend – Membership, User Registration, User Profile, User Directory & Content Restriction with Frontend Post Submission","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"wedevs\",\n                    \"product\": \"User Frontend – Membership, User Registration, User Profile, User Directory & Content Restriction with Frontend Post Submission\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"4.3.12\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4,"severity":"MEDIUM"}],"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"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-96574","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-96574","identifiers":["CVE-2026-96574"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
