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

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.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.2% (30-day exploitation probability)+1
  • Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Red Hat Pen Drive Powered by Red Hat Lightspeed, Red Hat Red Hat OpenShift Container Platform 4.19, Red Hat Red Hat OpenShift Container Platform 4.20…).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Exploitation requires user interaction: tighten email/web filtering and warn affected users.
  4. Search available logs for exploit probes, errors and authentication anomalies.

What should defenders know first?

CVE-2026-87114 is "Kube-compare: container:// reference extraction runs the image entrypoint and silently escalates to sudo", rated High. It affects Pen Drive Powered by Red Hat Lightspeed (Red Hat); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 7.1 describes technical severity. EPSS 0.20% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
