HTTP Client uses incorrect token after refresh
Impact
HTTP Clients created by AddUserAccessTokenHttpClient may use a different user's access token after a token refresh. This occurs because a refreshed token will be captured in pooled HttpClient instances, which may be used by a different user.
Workarounds
Instead of using AddUserAccessTokenHttpClient to create an HttpClient that automatically adds a managed token to outgoing requests, you can use the HttpConext.GetUserAccessTokenAsync extension method or the IUserTokenManagementService.GetAccessTokenAsync method.
