{"schema":"threatline.record/2","record":{"id":"CVE-2026-96574","aliases":[],"summary":"User Frontend <= 4.3.12 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'wpuf_payment_method' Parameter","details":"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.","categories":["Unclassified"],"product":"User Frontend – Membership, User Registration, User Profile, User Directory & Content Restriction with Frontend Post Submission","vendor":"wedevs","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-96574","source_modified_at":"2026-10-11T12:23:56.023Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"User Frontend – Membership, User Registration, User Profile, User Directory & Content Restriction with Frontend Post Submission","vendor":"wedevs","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.3.12","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.4,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00216,"percentile":0.11396,"score_date":"2026-10-23"},"published_at":"2026-10-10T06:40:09.032Z","modified_at":"2026-10-11T12:23:56.023Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-96574","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-11T12:23:56.023Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-96574","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/12f1cbc1-42c1-4ace-88ec-8aa981367c85?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.12/includes/Admin/List_Table_Transactions.php#L204"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.12/wpuf-functions.php#L2498"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.12/includes/Frontend/Payment.php#L566"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.12/Lib/Gateway/Bank.php#L102"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/wp-user-frontend/tags/4.3.12/includes/Frontend/Payment.php#L503"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset/3722911/wp-user-frontend/trunk/includes/Admin/List_Table_Transactions.php"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-11T12:14:19.401262Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-11T12:23:56.023Z","content_hash":"a5e9768b2e694845add8ff4e07cfd5cb2dd6de044825926f30c5b583c2e782c3"}}
