  "title": "Service account token exposure in KEDA Vault authentication",
  "summary": "KEDA versions through 2.20.2 can expose the operator ServiceAccount token through HashiCorp Vault authentication configured in a TriggerAuthentication resource. A namespace administrator who can create TriggerAuthentication and ScaledObject resources can direct the authentication request to a controlled endpoint and obtain the operator's permissions. The issue requires KEDA's default operator configuration and the relevant namespaced KEDA creation permissions.",
  "mitigation": "Upgrade github.com/kedacore/keda/v2 to version 2.21.0 or later. Until upgraded, prevent untrusted namespace administrators from creating TriggerAuthentication and ScaledObject resources, particularly configurations using HashiCorp Vault Kubernetes authentication.",
