Nomad

Host namespace escape in HashiCorp Nomad and Nomad Enterprise lets an authenticated job submitter bypass the allow_privileged control for the Docker task driver, launching containers in host PID/network/IPC namespaces to read data from the host or co-located workloads on the same client node. The flaw stems from missing authorization enforcement (CWE-862) and carries a CVSS 7.7 with a changed scope, reflecting cross-tenant impact. There is no public exploit identified at time of analysis and it is not listed in CISA KEV.
