CVE-2026-86226Public exploitNetwork attack vector

Stored XSS via unescaped profile email

Published Sep 6, 2026 · Updated Sep 8, 2026

Stored cross-site scripting in Projectworlds Online Attendance System 1.0 allows remote authenticated users to execute JavaScript via profile email. The profile-update flow accepts HTML-significant characters under an overly permissive email regular expression, stores the value, and profile.php writes it into a value attribute without output encoding. Any standard account can plant the payload, which runs when an authenticated user loads the profile and can read the non-HttpOnly session cookie.
