CVE-2026-32629Public exploitNetwork attack vector

Stored XSS via raw guest email rendering

Published Apr 2, 2026 · Updated Apr 2, 2026

Stored XSS in phpMyFAQ before 4.1.1 allows remote attackers to execute script in an administrator's browser via a guest FAQ email. The frontend FaqController accepts an RFC-valid quoted email containing HTML, stores it unsanitized, and the admin FAQ editor renders it with Twig's raw filter. Guest FAQ submission is enabled by default, but exploitation requires an administrator to open the pending FAQ; the script then acts with that browser session's privileges.
