Summary

The Raft RPC layer in HashiCorp Nomad and Nomad Enterprise has a vulnerability that allows non-server agents with valid certificates, signed by the same Certificate Authority (CA), to access functionalities typically reserved for server-only operations. This could result in unauthorized privilege escalation, potentially compromising the security of deployments. Users should ensure they update to version 1.0.10 or 1.1.4 to mitigate this risk.
