Description Huzaifa S. Sidhpurwala 2015-11-03 05:57:35 UTC
Security researcher Shinto K Anto reported an issue with cross-origin resource sharing (CORS) "preflight" requests when receiving certain Content-Type headers. This is due to an error in implementation resulting in trying to process multiple media types when they are returned in the Content-Type headers from a server. This is disallowed in the CORS specification and results in a simple instead of a "preflight" request, leading to potential same-origin policy violation.
