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."}],"affected":[{"vendor":"Red Hat","product":"Red Hat OpenShift Container Platform 4.19","collectionURL":"https://catalog.redhat.com/software/containers/","packageName":"openshift4/kube-compare-artifacts-rhel9","defaultStatus":"affected","versions":[{"version":"1790632105","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/a:redhat:openshift:4.19::el9"]},{"vendor":"Red Hat","product":"Red Hat OpenShift Container Platform 4.20","collectionURL":"https://catalog.redhat.com/software/containers/","packageName":"openshift4/kube-compare-artifacts-rhel9","defaultStatus":"affected","versions":[{"version":"1790707563","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/a:redhat:openshift:4.20::el9"]},{"vendor":"Red Hat","product":"Red Hat OpenShift Container Platform 4.21","collectionURL":"https://catalog.redhat.com/software/containers/","packageName":"openshift4/kube-compare-artifacts-rhel9","defaultStatus":"affected","versions":[{"version":"1790707362","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/a:redhat:openshift:4.21::el9"]},{"vendor":"Red Hat","product":"Red Hat OpenShift Container Platform 4.22","collectionURL":"https://catalog.redhat.com/software/containers/","packageName":"openshift4/kube-compare-artifacts-rhel9","defaultStatus":"affected","versions":[{"version":"1790718431","lessThan":"*","versionType":"rpm","status":"unaffected"}],"cpes":["cpe:/a:redhat:openshift:4.22::el9"]},{"vendor":"Red Hat","product":"Pen Drive Powered by Red Hat Lightspeed","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"pen-drive/pen-drive-scanner-rhel9","defaultStatus":"affected","cpes":["cpe:/a:redhat:pdrive_lightspeed:1"]}],"references":[{"url":"https://access.redhat.com/errata/RHSA-2026:74381","name":"RHSA-2026:74381","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2026:74384","name":"RHSA-2026:74384","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2026:74430","name":"RHSA-2026:74430","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/errata/RHSA-2026:74435","name":"RHSA-2026:74435","tags":["vendor-advisory","x_refsource_REDHAT"]},{"url":"https://access.redhat.com/security/cve/CVE-2026-87114","tags":["vdb-entry","x_refsource_REDHAT"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2522945","name":"RHBZ#2522945","tags":["issue-tracking","x_refsource_REDHAT"]}],"datePublic":"2026-09-28T16:15:00.000Z","problemTypes":[{"descriptions":[{"cweId":"CWE-829","description":"Inclusion of Functionality from Untrusted Control Sphere","lang":"en","type":"CWE"}]}],"x_redhatCweChain":"CWE-829: Inclusion of Functionality from Untrusted Control Sphere","workarounds":[{"lang":"en","value":"To mitigate this issue, users of `kube-compare` should ensure that any container images referenced via the `container://` scheme are from trusted sources.
