- Fixed an issue where `pull image` fails from a cross-subscription Azure Container Registry when using MSI to authenticate. ([#77245](https://github.com/kubernetes/kubernetes/pull/77245), [@norshtein](https://github.com/norshtein))

- The JWT authenticator in `kube-apiserver` now reports the following metrics when the `StructuredAuthenticationConfiguration` feature gate is enabled:
  - `apiserver_authentication_jwt_authenticator_jwks_fetch_last_timestamp_seconds`

 - Provides a fix to allow a cluster in a private Azure cloud to authenticate to ACR in the same cloud. ([#90425](https://github.com/kubernetes/kubernetes/pull/90425), [@DavidParks8](https://github.com/DavidParks8)) [SIG Cloud Provider]

For example, you could have code like this:

```Python
def get_current_user(token: str):
    # authenticate user
    return User()


@app.get("/items/")
def read_items(user: User = Depends(get_current_user)):
    ...


@app.post("/items/")

### CVE-2025-0426: Node Denial of Service via Kubelet Checkpoint API

A security issue was discovered in Kubernetes where a large number of container checkpoint requests made to the unauthenticated kubelet read-only HTTP endpoint may cause a Node Denial of Service by filling the Node's disk.

**Affected Versions**:
  - kubelet kubelet v1.30.0 to v1.30.9
  - kubelet v1.31.0 to v1.31.5
