How to fix?
Microsoft.IdentityModel.Clients.ActiveDirectory to version 5.2.0 or higher.
Microsoft.IdentityModel.Clients.ActiveDirectory is a package for adding authentication functionality to your .NET based client by taking advantage of Windows Server Active Directory and Azure Active Directory.
Affected versions of this package are vulnerable to Privilege Escalation in the way the library caches tokens. This allows an authenticated attacker to perform actions in context of another user.
