CVE-2026-19706: Red Hat OpenShift Agent-Based Installation privilege escalation in CSR approval

CVE-2026-19706 · Severity: high · CVSS 8.3 · Published 2026-11-09

Red Hat OpenShift's Agent-Based Installation (ABI) bootstrap process fails to validate identities when approving certificate signing requests, allowing an attacker with network access to request an administrative certificate and gain full cluster control. An attacker can exploit this by retrieving an unauthenticated configuration file from the bootstrap network, crafting a forged certificate request for system administrator privileges, and receiving a valid signed certificate that grants cluster-admin access. The vulnerability exists only during the brief bootstrap window before the cluster fully initializes.

Technologies: Red Hat OpenShift Container Platform. Vendors: Red Hat.

Technical details

The approve-csr.service in OpenShift ABI unconditionally approves all CertificateSigningRequests without validating the requester's identity, violating CWE-306 (Missing Authentication for Critical Functionality). An attacker with network adjacency to the bootstrap node can retrieve an Ignition file from ports 22623/22624, extract a limited kubeconfig, submit a CSR with CN=system:admin, and receive a valid signed certificate granting cluster-admin privileges. Exploitation requires network access to the bootstrap node's Kubernetes API and is limited to the narrow ABI bootstrap window.
