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

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

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.
