CVE-2026-71472Network attack vector

Authenticated code execution via WORK_MEM injection

Published Aug 17, 2026 · Updated Aug 20, 2026

Command injection in Red Hat Advanced Cluster Management for Kubernetes allows remote authenticated users to execute code via a crafted Search CR. The WORK_MEM value from a Search Custom Resource is used in postgresql-start.sh and an SQL query without validation or neutralization, enabling shell-command injection and SQL statement injection in the acm-search-v2-rhel9 search stack. Reachability requires hub administrator or Search CR editor access, and successful exploitation runs inside a privileged postgres pod with search-service compromise and cluster-wide impersonate privileges described by Red Hat.
