MiroFish CVE-2026-7058

No vendor-released patch exists at time of analysis - the project maintainer (666ghj) has not responded to the vulnerability disclosure submitted via GitHub issue #488 (https://github.com/666ghj/MiroFish/issues/488). Organizations must implement immediate compensating controls: (1) Remove all internet-facing exposure to MiroFish services by blocking external network access to affected ports/endpoints at firewall level - this prevents remote exploitation but eliminates legitimate remote access. (2) Implement strict network segmentation to isolate MiroFish instances on trusted internal networks with IP allowlisting for authorized clients only - reduces attack surface to insider threats and lateral movement scenarios. (3) Deploy web application firewall (WAF) or reverse proxy with command injection signature detection ahead of MiroFish endpoints, specifically filtering shell metacharacters (semicolons, pipes, backticks, dollar signs) in requests to simulation_ipc endpoints - may cause false positives if legitimate commands use these characters. (4) Monitor MiroFish process execution using EDR/auditd for unexpected child processes spawned from the Python backend, alerting on shell invocations (bash, sh, cmd.exe). (5) Consider migrating to alternative solutions or forking the project to apply input validation patches manually to SimulationIPCClient.send_command. Given vendor abandonment risk, long-term use of MiroFish poses unacceptable security debt.
