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

Quick assessment

Affected
Red Hat Pen Drive Powered by Red Hat Lightspeed
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 kube-compare 中发现了一个安全漏洞。当处理 引用路径时，该工具错误地执行了不受信任容器镜像的入口点（entrypoint），而不是仅仅从已停止的容器中提取数据。这使得远程攻击者能够在操作者的工作站上实现任意代码执行。如果 Docker 守护进程需要提权，不受信任的代码可能以通过守护进程提权获得的 root 权限执行，从而带来严重的安全风险。

Vulnerability Title
Kube-compare: container:// reference extraction runs the image entrypoint and silently escalates to sudo
Source: CVE Program / CVE List V5
Vulnerability Description
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.
