# GHSA-7cwm-fpfh-rrch: Ironic Standalone Operator's prometheus metrics exporter bound to all interfaces

> Attackers on adjacent networks can read operational metrics if the Prometheus exporter is enabled, as it binds to all interfaces without authentication.

## What is GHSA-7cwm-fpfh-rrch?

GHSA-7cwm-fpfh-rrch is a vulnerability in github.com/metal3-io/ironic-standalone-operator, published on 29 May 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official description

## Impact

The Ironic Standalone Operator (IRSO) is the operator to maintain an Ironic deployment for Metal3. The Prometheus metrics exporter binds to 0.0.0.0 (all network interfaces) by default with no authentication. The default config is disabled. If enabled, this exposes operational metrics to any host on adjacent networks. Deployments running IrSO v0.7.0 through v0.8.1 with the Prometheus exporter enabled are affected. Versions prior to v0.7.0 do not have the Prometheus exporter feature.

## Patches

The exporter now exposes a configurable bindAddress field. Users should upgrade to v0.9.0 or later. 

## Workarounds

Users on older versions than v0.9.0 should use host-level firewall rules (iptables/nftables) to restrict access to the metrics port from unintended networks, or disable the metrics service.

Affected packages and fixed versions:
- github.com/metal3-io/ironic-standalone-operator (Go): affected all versions; fixed in 0.9.0
- github.com/metal3-io/ironic-standalone-operator (Go): affected all versions; fixed in 0.9.0
- github.com/metal3-io/ironic-standalone-operator (Go): affected all versions; fixed in 0.9.0

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
