FKIE_CVE-2026-46711

Vulnerability from fkie_nvd - Published: 2026-09-30 17:16 - Updated: 2026-09-30 19:57
Severity
8.3 (High) - CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:L
Summary
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.
