CVE-2026-87114 — Kube-compare: container:// reference extraction runs the image entrypoint and silently escalates to sudo

Affected: Red Hat OpenShift Container Platform 4.19, Red Hat OpenShift Container Platform 4.20, Red Hat OpenShift Container Platform 4.21, Red Hat OpenShift Container Platform 4.22, Red Hat Pen Drive Powered by Red Hat Lightspeed

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.
