Description Jan Lieskovsky 2012-08-31 13:30:50 UTC
A cross-site request forgery flaw was found in the way MediaWiki, a wiki engine, protected CSRF tokens available via the API when X-Frame-Options headers were used. Previously it was possible for a remote attacker to obtain them and possibly perform CSRF attacks.
