Description Jan Lieskovsky 2009-09-25 18:24:55 UTC

A security flaw was found in the WebKit's Cross-Origin Resource Sharing (CORS)
implementation. Quoting exact details from the WebKit advisory:

Before allowing a page from one origin to access a resource in another origin, WebKit sends a preflight request, to determine if the origin server for the resource being accessed will allow the resource to be shared. WebKit includes custom HTTP headers specified by the requesting page in the preflight request. This can result in unexpected actions being initiated on the cross-origin site
without user consent. This issue is addressed by dropping custom HTTP
headers from preflight requests.
