CVE-2022-4212Public exploitNetwork attack vector

Reflected XSS via unescaped ipf filter value

Published Dec 2, 2022 · Updated Apr 8, 2026

Reflected XSS in Prasunsen Chained Quiz 1.3.2 and earlier allows remote attackers to execute scripts through a crafted ipf parameter. The chainedquiz_list view places the ipf filter value into an HTML attribute after sanitize_text_field processing instead of context-appropriate attribute escaping. Execution requires a logged-in administrator to open the crafted administrative URL, enabling script execution in that administrator's browser context.
