{"id":"CVE-2026-46711","state":"PUBLISHED","title":"Soft Machine: Unauthenticated workspace API exposes arbitrary file read & directory exfiltration to any peer on the Fly private network","description":"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.","publishedAt":"2026-09-30T16:30:02.745Z","updatedAt":"2026-09-30T17:02:21.234Z","severity":{"score":8.3,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["Soft-Machine-io security"],"affected":[{"vendor":"Soft-Machine-io","product":"security","versions":[{"version":"<= 0.2.247","status":"affected"}]}],"references":["https://github.com/Soft-Machine-io/security/security/advisories/GHSA-h6g6-qr45-qmrr"],"weaknesses":["CWE-306"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/46xxx/CVE-2026-46711.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-46711","state":"PUBLISHED","datePublished":"2026-09-30T16:30:02.745Z","dateUpdated":"2026-09-30T17:02:21.234Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-15T23:26:58.309Z"},"containers":{"cna":{"title":"Soft Machine: Unauthenticated workspace API exposes arbitrary file read & directory exfiltration to any peer on the Fly private network","descriptions":[{"lang":"en","value":"Soft Machine is a Virtual Machine–based agentic development environment / Cloud OS.
