CVE-2025-68143
Unknown Unknown - Not Provided
Arbitrary Directory Creation Vulnerability in MCP git_init Tool

Publication date: 2025-12-17

Last updated on: 2026-04-14

Assigner: GitHub, Inc.

Description
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.

Executive Summary

The vulnerability exists in the git_init tool of mcp-server-git versions prior to 2025.9.25. This tool accepted arbitrary filesystem paths and created Git repositories without validating the target location. Unlike other tools that required an existing repository, git_init could operate on any directory accessible to the server process, potentially allowing unauthorized git operations on those directories. The tool was removed in version 2025.9.25 to fix this issue.

Impact Analysis

This vulnerability can allow unauthorized creation and manipulation of Git repositories in arbitrary directories accessible to the server process. This could lead to unauthorized access or modification of files, potentially compromising data integrity or confidentiality within those directories.

Mitigation Strategies

Upgrade the mcp-server-git software to version 2025.9.25 or newer, as this version removes the vulnerable git_init tool. The server should only operate on existing repositories, and the git_init tool that allowed arbitrary filesystem path usage has been removed to prevent this vulnerability.
