Upgrade Gw2Sharp to version 0.3.1 or higher.
Overview
Gw2Sharp is a .NET wrapper library for the official Guild Wars 2 API.
Affected versions of this package are vulnerable to Information Exposure. When using an instance of MemoryCacheMethod and using it with multiple instances of Gw2WebApiClient, there's a possibility that cached authenticated responses will leak to another request to the same endpoint, but with a different Guild Wars 2 access token.
The latter request will not start however, and will return the first cached response immediately. This means that the second response (or later responses) may contain the same data as the first response, therefore leaking data from another authenticated endpoint.
