Description

Impact

A security vulnerability was discovered in Gardener when Terraformer is used for infrastructure provisioning. This vulnerability could allow a user with administrative privileges for a Gardener project to obtain control over the seed cluster where the shoot cluster is managed.

This CVE affects all Gardener installations where Terraformer is used/can be enabled for infrastructure provisioning with any of the affected components mentioned below.

Affected Components

• gardener-extension-provider-gcp • gardener-extension-provider-azure • gardener-extension-provider-openstack • gardener-extension-provider-aws

Affected Versions

• gardener-extension-provider-gcp < v1.46.0 • gardener-extension-provider-azure < v1.55.0 • gardener-extension-provider-openstack < v1.49.0 • gardener-extension-provider-aws < v1.64.0

Fixed versions

• gardener-extension-provider-gcp >= v1.46.0 • gardener-extension-provider-azure >= v1.55.0 • gardener-extension-provider-openstack >= v1.49.0 • gardener-extension-provider-aws >= v1.64.0

How do I mitigate this vulnerability?

Update to a fixed version.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/gardener/gardener-extension-provider-aws. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

  2. Fix

    Update github.com/gardener/gardener-extension-provider-aws to 1.64.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-227x-7mh8-3cf6 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 pinpoints whether GHSA-227x-7mh8-3cf6 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Tailored to GHSA-227x-7mh8-3cf6. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
