{"schema":"threatline.record/2","record":{"id":"CVE-2026-46711","aliases":["GHSA-h6g6-qr45-qmrr"],"summary":"Soft Machine: Unauthenticated workspace API exposes arbitrary file read & directory exfiltration to any peer on the Fly private network","details":"Soft Machine is a Virtual Machine–based agentic development environment / Cloud OS. In versions 0.2.247 and prior, the workspace HTTP service that listens on 0.0.0.0:8080 inside each sm-ws-* Fly Machine exposes endpoints (/health, /file/<path>, /archive/<dir>) without any authentication or origin check. Any host that can reach TCP/8080 on a workspace can read arbitrary files under that workspace's /workspace root and download whole project trees as tar archives. Because every workspace shares the same Fly private 6PN and resolves all peer addresses via the unauthenticated _instances.internal TXT record, every other sm-ws-* machine on the same Fly app/org is a reachable, unauthenticated attacker — the trust boundary (workspace owner ↔ everyone-else) is missing. At time of publication, there are no publicly known patches.","categories":["Unclassified"],"product":"security","vendor":"Soft-Machine-io","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-46711","source_modified_at":"2026-09-30T17:02:21.234Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"security","vendor":"Soft-Machine-io","versions":[{"version":"<= 0.2.247","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":8.3,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00275,"percentile":0.18851,"score_date":"2026-10-23"},"published_at":"2026-09-30T16:30:02.745Z","modified_at":"2026-09-30T17:02:21.234Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-46711","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-30T17:02:21.234Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-46711","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/Soft-Machine-io/security/security/advisories/GHSA-h6g6-qr45-qmrr","tags":["exploit"]}],"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":"2026-09-30T17:01:41.415498Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-09-30T17:02:21.234Z","content_hash":"41891578365a532ab5957de1656ccbdff9e9a7516f949185a0f734445c21edfa"}}
