Summary
It was discovered that in Mediawiki, a wiki engine, several API modules allowed anti-CSRF tokens to be accessed via JSONP. These tokens protect against cross site request forgeries and are confidential.
Solution
For the oldstable distribution (squeeze), this problem has been fixed in version 1.15.5-2squeeze6. For the stable distribution (wheezy), this problem has been fixed in version 1.19.5-1+deb7u1. For the testing distribution (jessie) and unstable distribution (sid), this problem has been fixed in version 1.19.8+dfsg-1. We recommend that you upgrade your mediawiki packages.
