More information:

A flaw was discovered in mediawiki, a wiki engine: thumb.php outputs wikitext messages as raw HTML, potentially leading to cross-site scripting (XSS).

For the stable distribution (wheezy), this problem has been fixed in version 1.19.20+dfsg-0+deb7u3; this version additionally fixes a regression introduced in the previous release, DSA-3100-1.

We recommend that you upgrade your mediawiki packages.
