CVE-2026-82976 · Severity: high · CVSS 7.1 · Published 2026-11-03

OpenShift's bare metal provisioning system includes a component that serves bootable images over an unprotected HTTP server on the provisioning network. An attacker with network access to the provisioning network can discover and download these images, then extract embedded credentials including cluster pull secrets and SSH keys used for cluster operations and infrastructure access.

## Technical details

The image-customization-controller registers an unauthenticated HTTP file server on port 8084 with a directory listing that enumerates all provisioned image filenames (which are UUIDs). Each image file embeds an Ignition configuration containing base64-encoded cluster pull secrets, optional SSH keys, and network configuration. An adjacent network attacker can enumerate UUIDs via directory listing, download any image, decode the Ignition config, and extract credentials. The vulnerability requires network access to the provisioning network and is mitigated only by reliance on UUID randomness for access control.
