CVE-2026-42302Public exploitNetwork attack vector

Unauthenticated code execution via exposed code-server

Published May 8, 2026 · Updated May 8, 2026

Missing authentication in FastGPT 4.14.10 through 4.14.12 allows remote attackers to execute code in the agent-sandbox container. The projects/agent-sandbox/entrypoint.sh script launches code-server with authentication disabled and listens on every interface at port 8080. An exposed container port is the only network gate; access opens the web IDE and its integrated terminal with the sandbox user's control.
