CVE-2026-32629 Details
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 "<script>alert(1)</script>"@evil.com. PHP'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's |raw filter, which bypasses auto-escaping entirely. This issue has been patched in version 4.1.1.
A stored cross-site scripting vulnerability has been identified in phpMyFAQ versions prior to 4.1.1. The issue allows an unauthenticated attacker to submit a guest FAQ containing a syntactically valid email address, per RFC 5321, that includes raw HTML, such as a script tag. PHP's FILTER_VALIDATE_EMAIL accepts this as valid. The email is saved in the database without proper HTML sanitization and is later displayed in the admin FAQ editor using Twig's raw filter, which completely bypasses auto-escaping. This vulnerability has been patched in phpMyFAQ version 4.1.1.
Users are advised to update phpMyFAQ to version 4.1.1 or later, where this vulnerability has been fixed.
