How to fix?

There is no fixed version for github.com/TykTechnologies/tyk/gateway.

Overview

github.com/TykTechnologies/tyk/gateway is a Tyk Gateway API

Affected versions of this package are vulnerable to Directory Traversal via the handleAddOrUpdateApi function.

This function is able to delete arbitrary JSON files on the disk where Tyk is running via the management API. The APIID is provided by the user and this value is then used to create a file on disk. If there is a file found with the same name then it will be deleted and then re-created with the contents of the API creation request.
