CVE-2023-1782Network attack vector

Unauthenticated job submission via client RPC forwarding

Published Apr 5, 2023 · Updated Feb 10, 2025

Authorization bypass in HashiCorp Nomad and Nomad Enterprise 1.5.0 through 1.5.2 allows remote attackers to submit cluster jobs. A client agent forwards an unauthenticated HTTP request through internal RPCs, where the server processes it without the intended ACL authorization. The endpoint must be reachable and mTLS disabled; successful exploitation permits unauthorized workloads to run with the submitted job's privileges.
