Excessive Privileges in search-v2-operator

Executive Summary

CVE-2026-70496 is a privilege escalation vulnerability in the search-v2-operator. The operator's ClusterRole grants it cluster-admin equivalent privileges, allowing it to impersonate users, modify RBAC settings, approve certificate signing requests, and manage ManifestWork. This excessive access exceeds what the operator needs for its intended function.
