Kube-compare: container:// reference extraction runs the image entrypoint and silently escalates to sudo

Type: advisorySource: Official CVE List1 source record

A flaw was found in kube-compare. When processing a 'container://' reference path, the tool incorrectly executes an untrusted container image's entrypoint instead of merely extracting data from a stopped container. This allows a remote attacker to achieve arbitrary code execution on the operator's workstation. If the Docker daemon requires elevated privileges, the untrusted code may execute with root-mediated daemon privileges, posing a significant security risk.
