CVE-2026-71471

Acm-search-v2-rhel9: search-v2-operator: hub search cr collector.imageoverride propagated to every spoke as arbitrary container image

Published Aug 12, 2026 CVSS 3.1 · 9 Critical EPSS 1.2% KEV · Not listed
Description
A flaw was found in acm-search-v2-rhel9. An attacker with administrative privileges on the hub cluster, specifically with patch access to the Search Custom Resource (CR), could exploit a vulnerability in the `Collector.ImageOverride` field. This allows the attacker to deploy an arbitrary container image across all managed clusters. The consequence is remote code execution (RCE), enabling the attacker to execute commands and potentially access sensitive information across the entire fleet of managed clusters.

Remediation

Vendor Workaround

To mitigate this issue, restrict patch access to the Search Custom Resource (CR) to only trusted and authorized hub administrators. This limits the ability of unauthorized principals to modify the `Collector.ImageOverride` field and deploy arbitrary container images across the managed fleet.
