AI-Generated

The vulnerability allows remote authenticated attackers to execute arbitrary code on the host operating system by exploiting a Host header bypass and unvalidated arguments in the 9Router application prior to version 0.5.2. This could lead to unauthorized command execution through malicious custom plugins. Organizations using affected versions of 9Router should prioritize updating to version 0.5.2 to mitigate this high-severity risk.

Original NVD Description

9Router is an AI router & token saver. Prior to 0.5.2, 9Router allows a remote authenticated attacker to achieve arbitrary code execution on the host operating system by combining a Host header bypass of localhost-only routes with unvalidated MCP plugin args passed to child_process.spawn(), allowing malicious custom plugins to execute commands through /api/mcp//sse. This issue is fixed in version 0.5.2.
