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.","categories":["Containers & cloud"],"product":"Mistral","vendor":"OpenStack","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93858","source_modified_at":"2026-10-08T17:56:35.058Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"Mistral","vendor":"OpenStack","versions":[{"lessThan":"20.1.1","status":"affected","version":"0","versionType":"semver"},{"lessThan":"21.0.1","status":"affected","version":"21.0.0","versionType":"semver"},{"lessThan":"22.0.1","status":"affected","version":"22.0.0","versionType":"semver"},{"status":"affected","version":"23.0.0","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93858","source_modified_at":"2026-10-08T17:56:35.058Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Mistral","ecosystem":null},"version":"20.1.1","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93858","source_modified_at":"2026-10-08T17:56:35.058Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Mistral","ecosystem":null},"version":"21.0.1","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-93858","source_modified_at":"2026-10-08T17:56:35.058Z","fetched_at":"2026-10-23T18:48:36.087640Z","package":{"name":"Mistral","ecosystem":null},"version":"22.0.1","basis":"first unaffected version stated in the CVE record"}],"cvss":8.7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00428,"percentile":0.36046,"score_date":"2026-10-23"},"published_at":"2026-10-08T17:28:58.167Z","modified_at":"2026-10-08T17:56:35.058Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-93858","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-08T17:56:35.058Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-93858","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://launchpad.net/bugs/2162100","tags":["exploit"]},{"source":"CVE List","url":"https://security.openstack.org/ossa/OSSA-2026-044.html"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"total","assessed_at":"2026-10-08T17:56:18.408754Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"vendor and product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-08T17:56:35.058Z","content_hash":"176b23ab4ac64bfa3994d8af651867f42ad6cd0bc5fd679da236c3ce7930960e"}}
