CVE-2026-71471
Full vulnerability record from the local CVENow database.
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.

"value": "Se encontró una falla en acm-search-v2-rhel9. Un atacante con privilegios administrativos en el clúster central, específicamente con acceso de parche al Recurso Personalizado de Búsqueda (CR), podría explotar una vulnerabilidad en el campo ’Collector.ImageOverride’. Esto permite al atacante desplegar una imagen de contenedor arbitraria en todos los clústeres gestionados. La consecuencia es ejecución remota de código (RCE), lo que permite al atacante ejecutar comandos y potencialmente acceder a información sensible en toda la flota de clústeres gestionados."
