What should I do about CVE-2026-72526?
Restrict who can create Applications on hub, enforce RBAC, validate/strip annotations, apply vendor patch when available
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
An attacker with rights to create Application CRs on the hub can target arbitrary managed clusters, forcing ArgoCD to apply attacker-controlled manifests leading to RCE or privilege escalation.
