Summary

phpMyFAQ prior to 4.1.1 allows an unauthenticated attacker to submit a guest FAQ with an RFC 5321-valid email address (quoted local part) containing raw HTML, such as "<script>alert(1)</script>"@evil.com. FILTER_VALIDATE_EMAIL accepts it, the email is stored without sanitization, and it is rendered in the admin FAQ editor using Twig's |raw filter, bypassing auto-escaping. This is patched in 4.1.1.

Risk Assessment

An attacker can execute arbitrary JavaScript in the administrator's browser, hijacking the session and performing actions on their behalf, potentially leading to data theft or further compromise.

Recommendation

Upgrade phpMyFAQ to version 4.1.1 or later. Additionally, consider validating and sanitizing email addresses before storage and avoiding the |raw filter for user data.

Original NVD description (English source)

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.
