{"id":"CVE-2026-46711","published":"2026-09-30T17:16:46.060","lastModified":"2026-09-30T19:57:08.043","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.","cvssScore":8.3,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:L","cwes":["CWE-306"],"vendors":[],"products":[],"references":[{"url":"https://github.com/Soft-Machine-io/security/security/advisories/GHSA-h6g6-qr45-qmrr","tags":[]},{"url":"https://github.com/Soft-Machine-io/security/security/advisories/GHSA-h6g6-qr45-qmrr","tags":[]}],"exploitRefs":[{"url":"https://github.com/Soft-Machine-io/security/security/advisories/GHSA-h6g6-qr45-qmrr","tags":[]},{"url":"https://github.com/Soft-Machine-io/security/security/advisories/GHSA-h6g6-qr45-qmrr","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw allows unauthorized access to arbitrary files within the workspace and the ability to download project trees, posing a significant security risk.","exploitability":"Exploitation is relatively easy given that the service is exposed without authentication, and any host can reach it via TCP/8080.","blast_radius":"The impact is high as every sm-ws-* machine on the same Fly app/org is vulnerable, allowing attackers to access and download sensitive data from any workspace.","remediation":"Upgrade to version 0.2.248 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["auth-bypass","file-access","web"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-10-05T08:42:47.616Z"}}
