containerd CRI image label propagation host command execution
containerd contains a vulnerability in its CRI plugin where labels from an image configuration (for example, LABEL instructions in a Dockerfile) are propagated to container labels without sanitization or validation. A crafted container image can therefore inject attacker-controlled label values into the resulting container metadata. If a downstream component or plugin consumes those container labels for operational behavior, this can lead to arbitrary command execution on the host. Reported examples include label-consuming plugins such as the restart-monitor binary:// logger. The issue does not require checkpoint/restore to be enabled.
