+    Due to incorrect use of a default URL, singularity action commands
+    (run/shell/exec) specifying a container using a library:// URI will
+    always attempt to retrieve the container from the default remote
+    endpoint (cloud.sylabs.io) rather than the configured remote
+    endpoint.  An attacker may be able to push a malicious container to
+    the default remote endpoint with a URI that is identical to the URI
+    used by a victim with a non-default remote endpoint, thus executing
+    the malicious container.
