OpenHands is software for AI-driven development. Starting in version 1.5.0, a Command Injection vulnerability exists in the `get_git_diff()` method at `openhands/runtime/utils/git_handler.py:134`. The `path` parameter from the `/api/conversations/{conversation_id}/git/diff` API endpoint is passed unsanitized to a shell command, allowing authenticated attackers to execute arbitrary commands in the agent sandbox. The user is already allowed to instruct the agent to execute commands, but this bypasses the normal channels. Version 1.5.0 fixes the issue.

GHSA-7h8w-hj9j-8rjw — OpenHands is Vulnerable to Command Injection through its Git Diff Handler

Affected: PyPI: openhands-ai

## Summary

A Command Injection vulnerability exists in the `get_git_diff()` method at `openhands/runtime/utils/git_handler.py:134`. The `path` parameter from the `/api/conversations/{conversation_id}/git/diff` API endpoint is passed unsanitized to a shell command, allowing authenticated attackers to execute arbitrary commands in the agent sandbox. The user is already allowed to instruct the agent to execute commands, but this bypasses the normal channels.

## Details

### Vulnerable Code Path

The vulnerability flows through these files:

1. **API Endpoint** (`openhands/server/routes/files.py:267-277`) ```python @app.get('/git/diff') async def git_diff( path: str, # <-- User input from HTTP request ... ): ... diff = await call_sync_from_async(runtime.get_git_diff, path, cwd) # No sanitization ```

2. **Runtime** (`openhands/runtime/base.py:1231-1233`) ```python def get_git_diff(self, file_path: str, cwd: str) -> dict[str, str]: self.git_handler.set_cwd(cwd) return self.git_handler.get_git_diff(file_path) # Passed directly ```

3. **Vulnerable Method** (`openhands/runtime/utils/git_handler.py:10-12, 134`) ```python # Command template with placeholder GIT_DIFF_CMD = 'python3 /openhands/code/openhands/runtime/utils/git_diff.py "{file_path}"'

# Line 134 - VULNERABLE: User input directly interpolated result = self.execute(self.git_diff_cmd.format(file_path=file_path), self.cwd) ```

4. **Shell Execution** (`openhands/runtime/utils/git_diff.py:25-…
