Hi all!

We have a problem and I'm not sure if it is a bug or I just configured something wrong.

We import messages with NNTP. Now, when I post a message on the NNTP site which has some Javascript code in it

<script type="text/javascript">alert('Hello World');</script>

the message is imported into FUDforum. The code gets executed when a user opens the topic with this message. I think this should not work as it opens an easy way to XSS.
It doesn't make a diffent which settings are set for the forum (Tag-Style is set to none for the user).

Did I do something wrong or can you confirm this?

Best regards and a merry christmas Wink

Tim

For a quick fix I inserted a new filter in the "Replacement & Censorship" which searches for ">" and replaces it with ">" But this has some other issues when creating messages it gets converted as well so the user sees > in the preview/forum message.
