This plugin contains a Reflected XSS vulnerability (views/eventbrite/import-eventbrite-events.php line 14).
If an administrator can be tricked into clicking on a link controlled by the attacker, then an attacker would also be able to automate anything an admin could do, for example creating and deleting user accounts and creating and deleting content. There would be almost no way to tell that this was happening, and it is easy to make these links very convincing.
Current state: Fixed
Configure the plugin by creating an Eventbrite account, creating an application, going through the OAuth process, etc.
Using a browser with no XSS prevention (e.g. firefox), visit the following URL:
