AI-suggested
Upgrade FastGPT to version 4.14.13 or later, where this vulnerability has been patched. Since this is not a cloud service, users must apply the update themselves to remediate the issue. Patch status is confirmed by the vendor's versioning information.
Description
FastGPT is an AI Agent building platform. From version 4.14.10 to before version 4.14.13, the agent-sandbox component of FastGPT is vulnerable to unauthenticated Remote Code Execution (RCE). The startup script entrypoint.sh initializes code-server with the --auth none flag and binds the service to all network interfaces (0.0.0.0:8080). This configuration allows any user with network access to the port to bypass authentication and gain full control over the sandbox environment. This issue has been patched in version 4.14.13.
