Thorsten Glaser discovered that the RSSReader extension for MediaWiki, a website engine for collaborative work, does not properly escape tags in feeds. This could allow a malicious feed to inject JavaScript into the MediaWiki pages.

For the stable distribution (squeeze), this problem has been fixed in version 2.3squeeze2.

For the testing distribution (wheezy), this problem will be fixed soon.

For the unstable distribution (sid), this problem has been fixed in version 2.11.
