CVE-2026-26287

Summary

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.
