CVE-2026-71472: Red Hat Advanced Cluster Management For Kubernetes 2.11

Critical severity, CVSS 9.1. EPSS: 0.9% chance of exploitation in the next 30 days.

A flaw was found in acm-search-v2-rhel9. This vulnerability allows an authenticated attacker, such as a hub administrator or a Search Custom Resource (CR) editor, to inject malicious shell commands or SQL statements. This occurs because the WORK_MEM string provided in the Search CR is not properly validated before being used in a bash script and an SQL query. Successful exploitation could lead to arbitrary code execution within the privileged postgres pod, potentially compromising the system.
