Version 2026.8.1 of Bitwarden’s self-host repository adds long-requested support for running the unified container fully rootless and with a read-only root filesystem, and 2026.8.2 follows up with cap_drop: ALL. If you self-host the password manager, upgrade now and re-check your Docker Compose before a container escape turns a missed patch into a vault theft.

Kubernetes v1.37 enables KubeletInUserNamespace by default: the kubelet, runtimes, and CNI plugins can now run as a non-root user inside a user namespace. Turn it on to confine container-breakout flaws away from host root.
