XSS in Wedevs User Frontend – Membership, Registration, Profile, Directory & Content Restriction With Post Submission

CVE-2026-96574

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.
