CVE-2024-9806Public exploitNetwork attack vector

Stored XSS via executable room field names

Published Oct 10, 2024 · Updated Oct 10, 2024

Stored cross-site scripting in classroombookings 2.8.0 through 2.8.6 allows remote authenticated users to run code in a room viewer's browser. The room add/edit page stores an administrator-supplied custom-field name and later outputs it without neutralizing executable markup when an affected room is viewed. Administrator access is required to plant the payload; a subsequent room view triggers the stored script and permits modification of page content in that browser session.
