CVE-2026-53488

Description

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.

Notes

alexmurray

Traditionally the containerd source package contained both the library and docker application. However, in releases that contain the containerd-app source package, the containerd source package contains only the library whilst the docker application itself is contained in the containerd-app package.
