CVE-2026-26287
Published:October 06, 2026
Updated:October 13, 2026
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.
