+== Why is this an issue?
+
+include::../../../shared_content/secrets/rationale.adoc[]
+
+If an attacker gains access to a Docker swarm token, they might be able to add new workers or managers to the swarm.
+
+=== What is the potential impact?
+
+An attacker with control over a manager or worker node might be able to access sensitive information pushed to those malicious nodes. If the compromised token allows joining a
+manager node to the swarm, this one could compromise other legitimate nodes by pushing
+malicious tasks to them.
