Description Pedro Sampaio 2021-05-27 20:24:37 UTC 
In singularity 3.7.2 and 3.7.3, action commands against library:// URIs erroneously always used the default remote endpoint (cloud.sylabs.io). 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.
