CVE-2026-71471
Acm-search-v2-rhel9: search-v2-operator: hub search cr collector.imageoverride propagated to every spoke as arbitrary container image
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.
