CVE-2025-71165Public exploitNetwork attack vector

Authenticated script execution via unencoded path reflection

Published Jan 14, 2026 · Updated Jan 14, 2026

Reflected XSS in Typesetter CMS 5.1 and earlier allows remote authenticated users to execute script through the Tools Status path parameter. include/admin/Tools/Status.php inserts the request's path value into the HTML response without context-appropriate output encoding. An authenticated attacker must induce another authenticated user to load the crafted response; the script then runs within that user's browser session.
