CVE-2026-42302: CWE-306: Missing Authentication for Critical Function in labring FastGPT
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.
AI Analysis
Technical Summary
FastGPT is an AI Agent building platform. Versions from 4.14.10 up to but not including 4.14.13 have a vulnerability in the agent-sandbox component where the startup script entrypoint.sh launches code-server with the '--auth none' flag and binds it to 0.0.0.0:8080. This configuration disables authentication and exposes the service to all network interfaces, allowing unauthenticated attackers with network access to execute arbitrary code remotely within the sandbox environment. The vulnerability is identified as CWE-306 (Missing Authentication for Critical Function). The vendor has patched this issue in version 4.14.13.
Potential Impact
The vulnerability allows unauthenticated remote attackers to execute arbitrary code on the affected FastGPT sandbox environment, leading to full compromise of the sandbox. This includes complete confidentiality, integrity, and availability impacts as indicated by the CVSS score of 9.8 (critical). There are no known exploits in the wild at the time of this report.
Mitigation Recommendations
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.
