FKIE_CVE-2025-68143
Vulnerability from fkie_nvd - Published: 2025-12-17 23:16 - Updated: 2026-09-30 23:10
Severity
Summary
Model Context Protocol Servers is a collection of reference implementations for the model context protocol (MCP). In mcp-server-git versions prior to 2025.9.25, the git_init tool accepted arbitrary filesystem paths and created Git repositories without validating the target location. Unlike other tools which required an existing repository, git_init could operate on any directory accessible to the server process, making those directories eligible for subsequent git operations. The tool was removed entirely, as the server is intended to operate on existing repositories only. Users are advised to upgrade to 2025.9.25 or newer to remediate this issue.

En versiones de mcp-server-git anteriores a 2025.9.25, la herramienta git_init aceptaba rutas de sistema de archivos arbitrarias y creaba repositorios Git sin validar la ubicaci\u00f3n de destino. A diferencia de otras herramientas que requer\u00edan un repositorio existente, git_init pod\u00eda operar en cualquier directorio accesible para el proceso del servidor, haciendo que esos directorios fueran elegibles para operaciones git posteriores. La herramienta fue eliminada por completo, ya que el servidor est\u00e1 destinado a operar solo en repositorios existentes. Se aconseja a los usuarios actualizar a 2025.9.25 o posterior para remediar este problema."
