出现漏洞的文件为 `gerapy/server/core/views.py`

```python
@api_view(['POST'])
@permission_classes([IsAuthenticated])
def project_file_read(request):
    """
    get content of project file
    :param request: request object
    :return: file content
    """
    if request.method == 'POST':
        data = json.loads(request.body)
        path = join(data['path'], data['label'])
        # binary file
        with open(path, 'rb') as f:
            return HttpResponse(f.read().decode('utf-8'))
```

参数 path 和 label 都为用户可控变量，登录后构造请求包

```python
