Identifier: CVE-2026-42302

Known exploitation: Not listed in the CISA Known Exploited Vulnerabilities catalog at the last check.
EPSS: 0.7%

Summary

FastGPT, an AI Agent building platform, has an unauthenticated Remote Code Execution flaw in its agent-sandbox component from version 4.14.10 to before 4.14.13. The startup script entrypoint.sh runs code-server with the --auth none flag and binds it to 0.0.0.0:8080, so any user with network access to that port can bypass authentication and gain full control of the sandbox environment.

Mitigation

Fixed in 4.14.13.
