External Secrets Operator: label enforcement bypass in webhook generator enables secret exfiltration PUBLISHED

Description (CNA)

External Secrets Operator reads information from a third-party service and automatically injects the values as Kubernetes Secrets. Starting in version 0.10.0 and prior to version 1.3.2, a bug in the `webhook` generator initialization order incorrectly cleared the label-enforcement flag (`EnforceLabels`) after it was set, resulting in the provider-side check for `external-secrets.io/type=webhook` being skipped (and the operation to succeed while it should have failed with `secret does not contain needed label 'external-secrets.io/type: webhook'. Update secret label to use it with webhook`. Version 1.3.2 contains a patch.
