| Doc Text: |
A flaw was found in External Secrets Operator. A user with permissions to create ExternalSecret resources can trick the operator into creating a Kubernetes Secret that automatically contains a long-lived token for a specified service account. This allows the user to impersonate any service account within the same namespace, bypassing direct permissions for token or secret creation. This vulnerability leads to privilege escalation.
