Stored XSS via session dropdown output
Published Oct 10, 2024 · Updated Oct 10, 2024
Stored XSS in classroombookings 2.8.7 allows remote authenticated users to execute script in visitors' browsers via a session name. The session editor saves an administrator-supplied Name value, and the Bookings page emits it into the Session dropdown without sufficient output encoding. Administrator access is required to store the payload; a later visit to the Bookings page triggers it in the visitor's browser context.
