Reflected XSS via unescaped session username
Published Jan 17, 2022 · Updated Aug 3, 2024
Reflected XSS in ICEcoder before 8.1 allows remote authenticated users to execute script in a browser through a crafted username. In editor.php, the multi-user information panel writes the session username directly into HTML without xssClean output encoding. Exploitation requires a privileged account and victim interaction; the script runs in the ICEcoder origin, enabling limited data access or modification.
