Hello Kubernetes Community,
A security issue was discovered in
secrets-store-sync-controller where an actor with access to the
controller logs could observe service account tokens. These tokens
could then potentially be exchanged with external cloud providers to
access secrets stored in cloud vault solutions. Tokens are only logged
when there is a specific error marshaling the parameters
sent to the providers.
This issue has been rated MEDIUM CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N (6.5), and assigned CVE-2025-7445
To check if tokens are being logged, examine the manager container log:
kubectl logs -l 'app.kubernetes.io/part-of=secrets-store-sync-controller' -c manager -f | grep --line-buffered "csi.storage.k8s.io/serviceAccount.tokens"
Upgrade to secrets-store-sync-controller v0.0.2+
Examine cloud provider logs for unexpected token exchanges, as well as unexpected access to cloud vault secrets.
