CVE-2026-53488

containerd is an open-source container runtime. In versions prior to 1.7.33, 2.3.2, 2.2.5, 2.1.9, and 2.0.10 the CRI plugin propagates labels from an image config LABEL instruction in Dockerfile to a container without validation. This may result in executing an arbitrary command on the host, via ...
