Overview

Affected versions of this package are vulnerable to Information Exposure. Containers launched through containerd's CRI implementation that share the same image may receive incorrect environment variables (including values defined for other containers). If the affected containers have different security contexts, this could lead to other issues such as sensitive information leakage.
