Nice... |

I'm not sure this is a valid report. As an admin you are allowed to put HTML in the description of a list. It only fires when you click the link and doesn't fire on the loading of the page. |

I'm going to close this, but feel free to comment and re-open if you disagree. |

Expected behavior
The removal of script tags is not sufficient to prevent an XSS attack. You must HTML Entity encode any output that is reflected back to the page
Impact
Commonly include transmitting private data, like cookies or other session information, to the attacker, redirecting the victim to web content controlled by the attacker, or performing other malicious operations on the user’s machine under the guise of the vulnerable site.
