What is CVE-2026-46711?
CVE-2026-46711 is a high-severity missing authorization vulnerability in Soft-Machine-io security, published on 30 Sep 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official 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.
Weakness: CWE-306
