Ironic Standalone Operator's controller modifies user-owned resources without consent

GHSA-hfc8-w5f4-3x6m

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (github.com/metal3-io/ironic-standalone-operator 0.8.2, 0.7.3), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

Impact The Ironic Standalone Operator (IRSO) is the operator to maintain an Ironic deployment for Metal3. IRSO controller automatically adds its environment label to user-provided Secrets and ConfigMaps without the resource owner's consent. A high-privilege controller modifying user-owned resources constitutes an unauthorized integrity violation. Deployments running IrSO v0.7.0 through v0.8.1 that reference user-provided Secrets or ConfigMaps (TLS certificates, BMC CA, trusted CA) are affected. Patches Fixed in v0.9.0, v0.8.2, v0.7.3. Workarounds Manually add the environment label (ironic-standalone-operator.metal3.io/environment) to all user-provided Secrets and ConfigMaps before they are referenced in the Ironic resource. This prevents the controller from modifying them.

# Patch Next advisory brief: GHSA-hfc8-w5f4-3x6m

Advisory: Ironic Standalone Operator's controller modifies user-owned resources without consent
IDs: GHSA-hfc8-w5f4-3x6m
Record: https://patchnext.com/advisories/ghsa-hfc8-w5f4-3x6m (revision 1, source checked 26 Oct 2026, 15:23 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 4.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: github.com/metal3-io/ironic-standalone-operator 0.8.2, 0.7.3. A vendor fix does not mean a deployment is fixed.

## Affected components
- Go github.com/metal3-io/ironic-standalone-operator: affected <= 0.7.2; >= 0.8.0, <= 0.8.1; fixed in 0.7.3, 0.8.2

## Suggested inspection (read-only)
- Go github.com/metal3-io/ironic-standalone-operator: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on github.com/metal3-io/ironic-standalone-operator.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-hfc8-w5f4-3x6m (GitHub-reviewed advisory GHSA-hfc8-w5f4-3x6m lists affected ranges: Go github.com/metal3-io/ironic-standalone-operator >=0 =0.8.0 <=0.8.1)

Commands are suggestions: review each one before running it.
