Unauthenticated simulation takeover via unvalidated IPC path
Published Apr 26, 2026 · Updated Apr 26, 2026
Command injection in 666ghj MiroFish 0.1.0 through 0.1.2 allows remote attackers to alter or stop running simulations via REST requests. SimulationRunner uses an unvalidated simulation_id to select a run directory, and SimulationIPCClient.send_command writes unsigned JSON commands there for the subprocess to trust and execute. No authentication, ownership check, or command-integrity validation is required; a network-reachable backend with an active target simulation permits prompt injection or immediate simulation shutdown.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0.1.0
- Affected versionversion=0.1.1
- Affected versionversion=0.1.2
