Overview

easymon Enables your monitoring infrastructure to easily query the status of your app server's health.

Affected versions of this package are vulnerable to Cross-site Scripting (XSS). When passing an invalid check name as parameter to the endpoint where the easymon routes are mounted, a 406 response with a body that contains the invalid check name unescaped is returned. A malicious JavaScript can be injected into that invalid name and be executed in Firefox.
