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.","state":0,"publishedAt":"2026-10-08T17:28:58.167+00:00","modifiedAt":"2026-10-08T17:56:35.058+00:00","affected":[{"ecosystem":"Vendor product","name":"Mistral","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"product\": \"Mistral\",\n                    \"repo\": \"https://opendev.org/openstack/mistral\",\n                    \"vendor\": \"OpenStack\",\n                    \"versions\": [\n                        {\n                            \"lessThan\": \"20.1.1\",\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"lessThan\": \"21.0.1\",\n                            \"status\": \"affected\",\n                            \"version\": \"21.0.0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"lessThan\": \"22.0.1\",\n                            \"status\": \"affected\",\n                            \"version\": \"22.0.0\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"23.0.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:L/SI:N/SA:N","score":8.7,"severity":"HIGH"}],"references":["https://launchpad.net/bugs/2162100","https://security.openstack.org/ossa/OSSA-2026-044.html"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-93858","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-93858","identifiers":["CVE-2026-93858"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
