CVE-2026-6118 Details
Description
A vulnerability was determined in AstrBotDevs AstrBot up to 4.22.1. Impacted is the function add_mcp_server of the file astrbot/dashboard/routes/tools.py of the component MCP Endpoint. This manipulation of the argument command causes command injection. The attack is possible to be carried out remotely. The exploit has been publicly disclosed and may be utilized. The project was informed of the problem early through an issue report but has not responded yet.
A command injection vulnerability has been identified in the MCP (Model Context Protocol) endpoint of AstrBotDevs AstrBot, affecting versions through 4.22.1. The vulnerability resides in the 'add_mcp_server' function within 'astrbot/dashboard/routes/tools.py'. It allows authenticated dashboard users to execute arbitrary system commands by manipulating the 'command' argument of the MCP server configuration. This exploitation occurs remotely, with the injected command executed immediately during a connection test, bypassing any validation or restrictions.
It is recommended to implement command allowlisting for the MCP server configurations, ensuring that only specified commands can be executed. Additionally, validating the 'args' field to reject arguments with shell metacharacters, separating the configuration saving from connection testing, adding confirmation dialogs for MCP server additions, and logging all MCP configuration changes with user attribution could help mitigate this vulnerability.
