Issue

Any user can execute JavaScript code on an administrator user's account by simply changing their name into an XSS payload. This can be used to create a denial of service condition, or make the administrator perform unauthorised actions.

Steps to reproduce

  1. Create a user with the lowest privileges
  2. Navigate to the 'My Account' section of the application
  3. Change the user's real name to a JavaScript payload, like asdf<img src=x onerror=alert(1)>
  4. Log out of the account.
  5. Log into an administrator account
  6. Navigate to the user list in the administrator's console
  7. Observe an alert box appear
