What is CVE-2026-71471?
CVE-2026-71471 is a critical code injection vulnerability in Red Hat Advanced Cluster Management for Kubernetes 2.11, published on 12 Aug 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official 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.
Weakness: CWE-829
