      "value": "External Secrets Operator reads information from a third-party service and automatically injects the values as Kubernetes Secrets. A vulnerability was discovered in the BeyondTrust provider implementation for External Secrets Operator versions 0.10.1 through 0.19.2. 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, violating security boundaries and potentially exposing sensitive credentials. In version 0.20.0, the provider code was updated to use the `resolvers.SecretKeyRef` utility, which enforces namespace validation and only allows cross-namespace access for `ClusterSecretStore` types. This ensures secrets are only retrieved from the correct namespace, mitigating the risk of unauthorized access. All users should upgrade to the latest version containing this fix. As a workaround, use a policy engine such as Kyverno or OPA to prevent using BeyondTrust provider and/or validate the `(Cluster)SecretStore` and ensure the namespace may only be set when using a `ClusterSecretStore`."

      "value": "External Secrets Operator lee información de un servicio de terceros e inyecta automáticamente los valores como Secrets de Kubernetes. Se descubrió una vulnerabilidad en la implementación del proveedor BeyondTrust para las versiones 0.10.1 a 0.19.2 de External Secrets Operator. El proveedor recuperaba previamente secretos de Kubernetes directamente, sin validar el contexto del namespace o el tipo de almacén de secretos. Esto permitía el acceso no autorizado a secretos entre namespaces, violando los límites de seguridad y exponiendo potencialmente credenciales sensibles. En la versión 0.20.0, el código del proveedor fue actualizado para usar la utilidad 'resolvers.SecretKeyRef', que aplica la validación del namespace y solo permite el acceso entre namespaces para tipos 'ClusterSecretStore'. Esto asegura que los secretos solo se recuperen del namespace correcto, mitigando el riesgo de acceso no autorizado. Todos los usuarios deberían actualizar a la última versión que contiene esta corrección. Como solución alternativa, use un motor de políticas como Kyverno u OPA para evitar el uso del proveedor BeyondTrust y/o validar el '(Cluster)SecretStore' y asegurar que el namespace solo pueda establecerse cuando se usa un 'ClusterSecretStore'."
