Description Jan Lieskovsky 2010-08-01 12:14:11 EDT
Tim Starling reported:
  [1] https://bugzilla.wikimedia.org/show_bug.cgi?id=24565#c0

a deficiency in the way MediaWiki processed private cache headers
for almost all API operations. Further exact flaw implications from Tim [1]:

A user's browser can be tricked into requesting private data with public
caching headers, via a CSRF-style attack on an external web page. The attacker
would cause the victim's browser to request private data with public caching
headers, then the attacker would download the same data from the intermediate
HTTP proxy, bypassing access controls.
