It was reported that the JSON content-type was not restrictive enough. Bottle treated "text/plain;application/json" as JSON, allowing attackers to bypass intended security mechanisms. From the upstream report, "For example Chrome will not allow cross-origin xmlhttprequests with the content type set to "application/json" but you can set it to "text/plain;application/json" instead and bottle will accept it.".
