Stored XSS via forged unsanitized settings update
Published Jun 13, 2022 · Updated Aug 3, 2024
Stored XSS in Quick Subscribe 1.7.1 and earlier allows remote attackers to inject script through a forged administrator settings request. The settings handler accepts POST fields such as label_qs without a CSRF token check and stores them without sanitizing or escaping their content. Exploitation requires a logged-in administrator to visit attacker-controlled content; the injected script then runs when the stored setting is rendered.
