# mcp-git-tools npm package: resolveBaseBranch flaw allows remote code execution

The @rog0x/mcp-git-tools 1.0.1 package, an MCP server for git operations, contains a flaw in its resolveBaseBranch function. Per the NVD entry, a remote attacker can use it to execute arbitrary code.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- `npm ls @rog0x/mcp-git-tools` to see whether the package is installed and at which version
- Look for `@rog0x/mcp-git-tools` in `package.json` and lockfiles of MCP server setups
- unknown whether the vulnerable code path is reached in typical use

## Fix

- Remove `@rog0x/mcp-git-tools` or move off version `1.0.1` if a fixed release exists; unknown which version fixes it
- Rotate any credentials available to the MCP server process if it ran exposed

## Timeline
