CERT Polska coordinated disclosure reports multiple vulnerabilities in Windu CMS 4.1 (fixed in build 2250) — including CSRF (several variants), broken access control enabling privileged GET-based deletion of Super Admins, stored XSS on login and page-editing endpoints, file-upload CSRF, user enumeration, and weak client-side brute-force protection — credited to Karol Czubernat.
