FKIE_CVE-2026-22822

Vulnerability from fkie_nvd - Published: 2026-01-21 22:15 - Updated: 2026-02-18 15:29
Severity ?
8.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H
Summary
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.
