Critical (9.4) in linuxfoundation containerd. EPSS 0.2% chance of exploitation in the next 30 days. Fixed in github.com/containerd/containerd 1.7.33.
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 a plugin that consumes container labels for some operations. This issue has been fixed in versions 1.7.33, 2.3.2, 2.2.5, 2.1.9, and 2.0.10.
