Security readout for executives and security teams

Hastymail2 versions before RC 8 may expose session cookies because HTTPS sessions did not mark the cookie as Secure. If that cookie is later sent over HTTP, someone positioned to intercept traffic could capture it and potentially use the session. Exposure appears limited to organizations still running legacy Hastymail2 before RC 8, especially where HTTP remains reachable or mixed HTTP/HTTPS access exists for the same application or cookie scope. Treat this as a targeted legacy exposure issue, not a broad emergency. Prioritize if Hastymail2 is internet-facing, handles sensitive mail, or still permits HTTP access. Mitigation focus: Identify any Hastymail2 deployments and determine whether they are before RC 8.; Review Hastymail vendor security guidance before changing production systems.; Upgrade away from Hastymail2 versions before RC 8 where applicable..
