Summary
@cyanheads/git-mcp-server is an MCP server designed to interact with Git repositories. Prior to version 2.1.5, there is a command injection vulnerability caused by the unsanitized use of input parameters within a call to child_process.exec, enabling an attacker to inject arbitrary system commands. Successful exploitation can lead to remote code execution under the server process's privileges. The server constructs and executes shell commands using unvalidated user input directly within command-line strings. This introduces the possibility of shell metacharacter injection (|, >, &&, etc.). An MCP Client can be instructed to execute additional actions for example via indirect prompt injection when asked to read git logs. This issue has been patched in version 2.1.5.

"value": "@cyanheads/git-mcp-server es un servidor MCP dise\u00f1ado para interactuar con repositorios Git. Antes de la versi\u00f3n 2.1.5, exist\u00eda una vulnerabilidad de inyecci\u00f3n de comandos causada por el uso no autorizado de par\u00e1metros de entrada en una llamada a child_process.exec, lo que permit\u00eda a un atacante inyectar comandos arbitrarios del sistema. Una explotaci\u00f3n exitosa puede provocar la ejecuci\u00f3n remota de c\u00f3digo con los privilegios del proceso del servidor. El servidor construye y ejecuta comandos de shell utilizando entradas de usuario no validadas directamente dentro de las cadenas de la l\u00ednea de comandos. Esto introduce la posibilidad de inyecci\u00f3n de metacaracteres de shell (|, \u0026gt;, \u0026amp;\u0026amp;, etc.). Se puede indicar a un cliente MCP que ejecute acciones adicionales, por ejemplo, mediante la inyecci\u00f3n indirecta de prompts cuando se le solicita que lea los registros de Git. Este problema se ha corregido en la versi\u00f3n 2.1.5."
