High
| Vector | AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N |
Name of the Vulnerable Software and Affected Versions
External Secrets Operator versions 0.10.1 through 0.19.2
Description
The External Secrets Operator reads information from a third-party service and automatically injects the values as Kubernetes Secrets. A flaw exists in the BeyondTrust provider implementation where the provider previously retrieved Kubernetes secrets directly, without validating the namespace context or the type of secret store. This allowed unauthorized cross-namespace secret access, potentially exposing sensitive credentials. The issue was addressed in version 0.20.0 by using the
resolvers.SecretKeyRef utility, which enforces namespace validation and restricts cross-namespace access to ClusterSecretStore types.Recommendations
Upgrade to External Secrets Operator version 0.20.0 or later.
As a workaround, use a policy engine such as Kyverno or OPA to prevent using the BeyondTrust provider.
As a workaround, validate the
(Cluster)SecretStore and ensure the namespace may only be set when using a ClusterSecretStore.Exploit
Fix
Improper Access Control
