CVE-2025-68145mcp-server-git has missing path validation when using --repository flag
Medium 6.4
In plain English
A medium-severity path traversal in servers from modelcontextprotocol. There are no confirmed reports of exploitation so far. The chance it is exploited in the next 30 days is estimated at 7.0% (higher than 94% of all known vulnerabilities). Fixed versions are available - upgrade the affected package.
Official description
In mcp-server-git versions prior to 2025.12.17, when the server is started with the --repository flag to restrict operations to a specific repository path, it did not validate that repo_path arguments in subsequent tool calls were actually within that configured path. This could allow tool calls to operate on other repositories accessible to the server process. The fix adds path validation that resolves both the configured repository and the requested path (following symlinks) and verifies the requested path is within the allowed repository before executing any git operations. Users are advised to upgrade to 2025.12.17 upon release to remediate this issue.
