CVE-2024-4957Public exploitNetwork attack vector

Stored XSS via unescaped checklist names

Published Jun 26, 2024 · Updated Aug 1, 2024

Stored XSS in Jonas Breuer Frontend Checklist 2.3.2 and earlier allows remote authenticated users to execute scripts via checklist names. The checklist creation page stores the name field without adequate sanitization, and the admin listing page renders it without output escaping. Administrator privileges and a victim who opens the checklist listing are required; the stored script then runs in that browser even when unfiltered_html is disabled.
