app already contains its own authentication mechanism. As such, users first have to authenticate by way of the existing app to access VTAdmin-web. In this case, a trust boundary exists between the internet Vtctld over GRPC. At this stage the request is already authenticated, and if an attacker can find a way to read traffic, they are potentially able to bypass authentication and assume the highest level of of complete documentation on VTAdmins security could result in users unknowingly using VTAdmin in a way that is known to be insecure, and is either not documented, or the user will have to read the docs

goals in the future. Most of these results are vulnerable code snippets that did not provide an easy way to be called. Conclusively, while a vulnerability is present, an exploit might not always be possible
