{"id":"CVE-2026-93858","published":"2026-10-08T18:18:30.817","lastModified":"2026-10-08T21:10:41.427","description":"In OpenStack Mistral through 23.0.0, the std.ssh_proxied action passes a caller-supplied proxy_command value directly to paramiko.ProxyCommand() before any SSH connection to a gateway or target host is attempted. An authenticated project member can use the standard action-execution API to submit an arbitrary local command as proxy_command; paramiko starts that command as a subprocess on the executor host under the executor's own service account, independent of whether the SSH connection itself ever succeeds. Only Mistral deployments that permit the std.ssh_proxied action, the default configuration, are affected.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-78"],"vendors":[],"products":[],"references":[{"url":"https://launchpad.net/bugs/2162100","tags":[]},{"url":"https://security.openstack.org/ossa/OSSA-2026-044.html","tags":[]},{"url":"https://launchpad.net/bugs/2162100","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
