Description Huzaifa S. Sidhpurwala 2012-11-17 11:32:40 UTC 
Mozilla developer Gabor Krizsanits discovered that XMLHttpRequest objects created within sandboxes have the system principal instead of the sandbox principal. This can lead to cross-site request forgery (CSRF) or information theft via an add-on running untrusted code in a sandbox.
