* The `--audit-policy-file` option is required if the `AdvancedAuditing` feature is not explicitly turned off (`--feature-gates=AdvancedAuditing=false`) on the API server.
  * The audit log file defaults to JSON encoding when using the advanced auditing feature gate.
  * An audit policy file without either an `apiVersion` or a `kind` field may be treated as invalid.

reported to the request client in HTTP Warning headers, with a warning code of 299. Warnings can be sent both for allowed or denied admission responses.\n\n\"Audit\" specifies that a validation failure is included in the published audit event for the request. The audit event will contain a `validation.policy.admission.k8s.io/validation_failure` audit annotation with a value containing the details of the validation failures, formatted as a JSON list of objects, each with the following fields: - message:...

- Kube-apiserver: `--audit-log-version` and `--audit-webhook-version` now only support the default value of `audit.k8s.io/v1`. The v1alpha1 and v1beta1 audit log versions, deprecated since 1.13, have been removed. ([#108092](https://github.com/kubernetes/kubernetes/pull/108092), [@carlory](https://github.com/carlory))

- `kube-apiserver` added:
  - `alpha` support (guarded by the `ServiceAccountTokenJTI` feature gate) for adding a `jti` (JWT ID) claim to service account tokens it issues, adding an `authentication.kubernetes.io/credential-id` audit annotation in audit logs when the tokens are issued, and `authentication.kubernetes.io/credential-id` entry in the extra user info when the token is used to authenticate.

  - kube-apiserver v1.25.4
  - kube-apiserver v1.24.8
  - kube-apiserver v1.23.14
  - kube-apiserver v1.22.16

This vulnerability was reported by Richard Turnbull of NCC Group as part of the Kubernetes Audit


**CVSS Rating:** Medium (6.5) [CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N](https://www.first.org/cvss/calculator/3.0#CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N)

- Updated an audit annotation key used by the `…/serviceaccounts/<name>/token` resource handler.

- Added `auditAnnotations` to `ValidatingAdmissionPolicy`, enabling CEL to be used to add audit annotations to request audit events.
  Added `validationActions` to `ValidatingAdmissionPolicyBinding`, enabling validation failures to be handled by any combination of the warn, audit and deny enforcement actions. ([#115973](https://github.com/kubernetes/kubernetes/pull/115973), [@jpbetz](https://github.com/jpbetz))
