Description

phpMyFAQ is an open source FAQ web application. Prior to version 4.1.1, an unauthenticated attacker can submit a guest FAQ with an email address that is syntactically valid per RFC 5321 (quoted local part) yet contains raw HTML — for example "alert(1)"@evil.com. PHP&#39;s FILTER_VALIDATE_EMAIL accepts this email as valid. The email is stored in the database without HTML sanitization and later rendered in the admin FAQ editor template using Twig&#39;s |raw filter, which bypasses auto-escaping entirely. This issue has been patched in version 4.1.1.
