Description
Security researcher Masato Kinugawa reported that opening a
target page using a POST to the url prefixed with the feed:
protocol disables the mixed content blocker for that page. This could allow for
the risk of a man-in-the-middle (MITM) scripting attack on pages that
accidentally include insecure content which would otherwise be blocked.
