AI risk analysis

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.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to version 0.2.248 or later.

NVD 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.
