ruflo MCP Bridge

ruflo MCP Bridge - Unauthenticated RCE via terminal_execute

ruflo MCP bridge (< 3.16.3) in its default docker-compose deployment exposes POST /mcp with no authentication and binds to all interfaces (0.0.0.0:3001). The executeTool() function has no server-side deny list for dangerous tools, allowing an unauthenticated attacker to invoke tools/call with ruflo__terminal_execute, which runs execSync(command) on attacker-supplied input. This yields arbitrary command execution as the node user (uid 1000) inside the bridge container. The blocklist (AUTOPILOT_BLOCKED_PATTERNS + isBlockedTool()) is enforced only in the autopilot SSE handler; POST /mcp and POST /mcp/:group bypass it entirely.
