Endpoint Vulnerability

Feed protocol with POST bypasses mixed content protections

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.
