CVE-2022-3259Network attack vector

Traffic interception via omitted HSTS response header

Published Dec 9, 2022 · Updated Apr 22, 2025

Missing HSTS in Red Hat OpenShift Container Platform 4.9 allows man-in-the-middle attackers to intercept browser traffic. Red Hat does not identify the affected endpoint, but its HTTPS response omits Strict-Transport-Security, so browsers do not force later requests to HTTPS. An attacker must control the network path before HSTS is established; successful interception exposes or alters browser traffic without interrupting service.
