Updated

Cleartext Transmission of Sensitive Information has been reported in libsoup’s HTTP CONNECT handling. When establishing HTTPS tunnels via soupsession.c::tunnelconnect(), cookies (including potentially sensitive session cookies) are sent in cleartext within the initial HTTP CONNECT request to the configured proxy. A network-positioned attacker or malicious HTTP proxy can intercept or observe these cookies and leverage them for session hijacking or user impersonation.
