WebKit contains a flaw in the 'DocumentThreadableLoader::preflightFailure' function [WebCore/loader/DocumentThreadableLoader.cpp] that allows a Cross-site Request Forgery (CSRF / XSRF) attack. The flaw exists because the application allows bypassing the XDC check on synchronous preflighted requests. With a specially crafted web page, a context-dependent attacker can perform actions on another site in the trust relationship of the target user and site.
