CVE-2026-42302

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...

CVE-2026-42343

CVE-2026-42343 (FastGPT) affects FastGPT’s code-sandbox in versions ≤ 4.14.13, due to insufficient resource isolation. The system relies on an application-level soft limit (500 ms polling) for memory management and lacks OS-level constraints (cgroups/kernel namespaces). This enables time-window b...

CVE-2026-42343 FastGPT: Uncontrolled Resource Consumption leading to Sandbox Exhaustion

FastGPT is an AI Agent building platform. In versions 4.14.13 and prior, the code-sandbox component suffers from insufficient resource isolation and uncontrolled resource consumption. The service relies solely on an application-level soft limit a 500ms polling interval for memory management and...

CVE-2026-32128

FastGPT is an AI Agent building platform. In 4.14.7 and earlier, FastGPT's Python Sandbox fastgpt-sandbox includes guardrails intended to prevent file writes static detection + seccomp. These guardrails are bypassable by remapping stdout fd 1 to an arbitrary writable file descriptor using fcntl...

CVE-2026-32128

FastGPT’s Python Sandbox (fastgpt-sandbox) in versions 4.14.7 and earlier contains guardrails intended to block file writes (static detection + seccomp). The vulnerability arises because stdout (fd 1) can be remapped to an arbitrary writable file descriptor via fcntl. After remapping, writes thro...
