SCA: security update for github.com/external-secrets/external-secrets (GHSA-77v3-r3jw-j2v2)

critical Tenable Self-Hosted Container Security Plugin ID 436826

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - External Secrets Operator reads information from a third-party service and automatically injects the
 values as Kubernetes Secrets. Starting in version 0.20.2 and prior to version 1.2.0, the `getSecretKey`
 template function, while introduced for senhasegura Devops Secrets Management (DSM) provider, has the
 ability to fetch secrets cross-namespaces with the roleBinding of the external-secrets controller,
 bypassing our security mechanisms. This function was completely removed in version 1.2.0, as everything
 done with that templating function can be done in a different way while respecting External Secrets
 Operator's safeguards As a workaround, use a policy engine such as Kubernetes, Kyverno, Kubewarden, or OPA
 to prevent the usage of `getSecretKey` in any ExternalSecret resource. (CVE-2026-22822)
