redhat acm CVE-2026-70495 is a vulnerability in Red Hat Acm
Published on August 17, 2026

Search-v2-operator: search-v2-operator: cluster-wide impersonate on users/groups shared across 4 pods grants hub system:masters
A flaw was found in search-v2-operator. This component's `search-serviceaccount` has overly broad permissions, allowing it to impersonate users and groups across the entire cluster. If an attacker gains access to any of the pods running under this service account, they could exploit this to achieve `system:masters` access, granting them full control over the cluster.
