Description
GitHub Kanban MCP Server is a Model Context Protocol (MCP) server for managing GitHub issues in Kanban board format and streamlining LLM task management. Version 0.3.0 of the MCP Server is written in a way that is vulnerable to command injection vulnerability attacks as part of some of its MCP Server tool definition and implementation. The MCP Server exposes the tool `add_comment` which relies on Node.js child process API `exec` to execute the GitHub (`gh`) command, is an unsafe and vulnerable API if concatenated with untrusted user input. As of time of publication, no known patches are available.

Technical Context
Command injection allows an attacker to execute arbitrary OS commands on the host system through a vulnerable application that passes user input to system shells. This vulnerability is classified as OS Command Injection (CWE-78).
Affected Products
Affected: Kanban board format and streamlining LLM task management
Remediation
Avoid passing user input to system commands. Use language-specific APIs instead of shell commands. If unavoidable, use strict input validation and escaping.
