| CVE-2026-47680 | 1 Fluxcd | 1 Source-controller | 2026-09-11 | N/A |
| The source-controller is a Kubernetes operator, specialised in artifacts acquisition from external sources such as Git, OCI, Helm repositories and S3-compatible buckets. In versions 0.0.17 through 1.8.4, an actor with the ability to influence the contents of a bucket referenced by a `Bucket` resource can cause source-controller to write fetched object data to paths outside the per-reconciliation working directory. The corruption surface is bounded by source-controller's own and downstream Flux controllers' digest verification: source-controller verifies stored artifact digests during reconciliation and rebuilds on divergence; consumers (kustomize-controller, helm-controller) verify the digest of fetched artifacts and reject mismatches. These checks prevent a manipulated artifact from reaching the cluster, but an attacker can still write files anywhere the source-controller pod has permission to write. Separately, a user with permission to create or update `GitRepository` resources can cause source-controller to test for the existence of paths outside the cloned repository. Because the result is exposed via the resource's status, this allows limited enumeration of file paths on the controller pod. This surface exists only on source-controller v1.6.0 and later, where the sparse-checkout feature was introduced. This vulnerability was fixed in source-controller v1.8.5. There is no in-product workaround. Users should upgrade to a patched version. As a defense-in-depth measure for the GitRepository sparse-checkout surface, a `ValidatingAdmissionPolicy` (or a third-party policy engine such as Kyverno or OPA Gatekeeper) can be deployed to reject `GitRepository` resources whose `.spec.sparseCheckout` entries contain `..` or absolute path segments. | ||||
| CVE-2024-31216 | 1 Fluxcd | 1 Source-controller | 2026-04-15 | 5.1 Medium |
| The source-controller is a Kubernetes operator, specialised in artifacts acquisition from external sources such as Git, OCI, Helm repositories and S3-compatible buckets. The source-controller implements the source.toolkit.fluxcd.io API and is a core component of the GitOps toolkit. Prior to version 1.2.5, when source-controller was configured to use an Azure SAS token when connecting to Azure Blob Storage, the token was logged along with the Azure URL when the controller encountered a connection error. An attacker with access to the source-controller logs could use the token to gain access to the Azure Blob Storage until the token expires. This vulnerability was fixed in source-controller v1.2.5. There is no workaround for this vulnerability except for using a different auth mechanism such as Azure Workload Identity. | ||||
| CVE-2022-39272 | 1 Fluxcd | 7 Flux2, Helm-controller, Image-automation-controller and 4 more | 2025-04-23 | 5 Medium |
| Flux is an open and extensible continuous delivery solution for Kubernetes. Versions prior to 0.35.0 are subject to a Denial of Service. Users that have permissions to change Flux’s objects, either through a Flux source or directly within a cluster, can provide invalid data to fields `.spec.interval` or `.spec.timeout` (and structured variations of these fields), causing the entire object type to stop being processed. This issue is patched in version 0.35.0. As a workaround, Admission controllers can be employed to restrict the values that can be used for fields `.spec.interval` and `.spec.timeout`, however upgrading to the latest versions is still the recommended mitigation. | ||||
