What is CVE-2026-71566 and which systems are affected?

CVE-2026-71566 is a critical missing-authentication vulnerability (CWE-306) in FakeFish, the Redfish-compatible BMC emulator maintained by the openshift-metal3 project. When deployed with the KubeVirt backend, FakeFish ignores supplied credentials and relies solely on a mounted KUBECONFIG file for cluster access. Any user with network access to the FakeFish endpoint can issue commands without authentication, potentially manipulating virtual machines (VMs) owned by the instance. All git revisions from the initial commit through commit 28f9a6b are vulnerable. The issue is fixed in commit 526550a (with credential-mount enforcement at 5889d2c). CVE Record. Note: Only FakeFish instances running the KubeVirt backend and reachable over the network are affected.

What is the severity and impact of CVE-2026-71566?

CVE-2026-71566 has a CVSS v3.1 base score of 9.3 (Critical). The vulnerability allows any network client to manipulate VMs, including powering them on/off and mounting arbitrary virtual media, which can lead to denial of service or further compromise. The CVSS vector is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:H, indicating high availability impact, low integrity impact, and no confidentiality impact. Note: The vulnerability does not impact confidentiality but poses significant risks to availability and integrity.

How can organizations mitigate or remediate CVE-2026-71566?

To mitigate CVE-2026-71566, upgrade FakeFish to a version built from commit 526550a or later and ensure the credential-mount enforcement is active. For direct/binary deployments, start with the --validate-credentials flag. For container deployments, mount valid credentials at /tmp/fakefish-credentials; without this, the patched FakeFish will refuse to start. If immediate patching is not possible, deploy an authentication proxy in front of FakeFish and restrict network access to trusted hosts. Review exposed routes and audit VM activity for unauthorized access. Note: Delaying patching increases risk of exploitation.

CVE-2026-71566 – Authentication Bypass / Unauthorized VM Control – FakeFish (openshift-metal3) up to

Be the first to know when new zero-days emerge:

Summary

CVE-2026-71566 is a critical missing-authentication vulnerability (CWE-306) in FakeFish, the Redfish-compatible BMC emulator maintained by the openshift-metal3 project used to manage KubeVirt-backed virtual "bare metal" hosts. When FakeFish is deployed against the KubeVirt backend, it silently ignores the credentials supplied in incoming requests and instead relies solely on a mounted KUBECONFIG file for cluster access, meaning any user who can reach the FakeFish endpoint can issue commands with no valid authentication at all. The issue carries a CVSS v3.1 base score of 9.3 (Critical) and can result in unauthorized power control and virtual media manipulation of victim VMs.

Technical details

  • Root cause: FakeFish’s credential-validation logic is designed for physical BMC hardware, where supplied credentials are passed through to vendor scripts that validate them against the actual hardware BMC. The KubeVirt backend, however, never validates the supplied credentials — it authenticates to the Kubernetes cluster using a mounted KUBECONFIG file regardless of what credentials (if any) are presented in the request.
  • Trigger conditions: Any FakeFish instance running the KubeVirt backend that is reachable over the network (including via routes configured per the documented deployment pattern) is exploitable without any prior authentication.
  • Attack vector: Network (AV:N), no privileges required (PR:N), no user interaction (UI:N) — an attacker only needs network access to the FakeFish Redfish API endpoint.
  • Impact: Any cluster user (or unauthenticated network client, depending on exposure) can manipulate virtual machines belonging to the FakeFish instance’s owner, including powering VMs on/off and mounting arbitrary/unauthorized virtual CD images — enabling denial of service and potential follow-on compromise via malicious virtual media. The CVSS vector reflects no confidentiality impact, low integrity impact, and high availability impact (C:N/I:L/A:H).

Affected software

  • Product: FakeFish (openshift-metal3/fakefish)
  • Vulnerable range: All git revisions from the initial commit through commit 28f9a6b
  • Fixed in: Commit 526550a (with the credential-mount enforcement implemented at 5889d2c)

Severity

  • CVSS v3.1 Base Score: 9.3 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:H

Mitigation and recommended actions

  • Immediate: Upgrade FakeFish to a version built from commit 526550a or later, and ensure the fix’s enforcement mechanism is active:
    • Direct/binary deployments must be started with the --validate-credentials flag.
    • Containerfile-based deployments must mount valid credentials at /tmp/fakefish-credentials; without this mount, the patched FakeFish will refuse to start, preventing insecure operation.
  • If immediate patching is not possible: Deploy an authentication proxy in front of FakeFish to enforce access control before requests reach the FakeFish service, and restrict network reachability of the FakeFish endpoint/route to trusted hosts only.
  • Review any exposed FakeFish routes for unnecessary external network exposure and audit VM power/media-mount activity for signs of unauthorized access during the exposure window.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
