Title
Apache Traffic Server: Default server_session_sharing.match omits MASK_CERT, allowing pooled mTLS identity confusion at the origin
Summary
Apache Traffic Server's default outbound session-sharing policy can reuse a pooled TLS session authenticated with one client certificate for a transaction configured to present a different one. This issue affects Apache Traffic Server: from 9.0.0 through 9.2.15, from 10.0.0 through 10.1.4, 10.2.0. Users are recommended to upgrade to version 9.2.16, 10.1.5, or 10.2.1, which fix the issue.
