Summary
FastGPT versions 4.14.10 through 4.14.13 contain an unauthenticated Remote Code Execution (RCE) vulnerability in the agent-sandbox component. 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), allowing any user with network access to bypass authentication and gain full control over the sandbox environment.
Risk Assessment
An unauthenticated attacker can gain full control over the sandbox environment, potentially leading to arbitrary code execution and further attacks on other systems.
Recommendation
Immediately upgrade FastGPT to version 4.14.13 or later, which includes a fix for this vulnerability.
Original NVD description (English source)
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.
