Doc Text:
A flaw was found in containerd, an open-source container runtime. The Container Runtime Interface (CRI) plugin, which manages container operations, fails to validate labels propagated from an image configuration to a container. This oversight could enable an attacker to execute arbitrary commands on the host system through a plugin that processes these unvalidated labels. The primary impact is host-root command execution, allowing unauthorized control over the underlying system.

Description OSIDB Bzimport 2026-07-01 02:01:32 UTC 
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.
