MEDIUM

HTTP Client uses incorrect token after refresh

Published November 7, 2024Updated November 8, 2024Source: osv

Summary

### 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. ### Patches This issue is fixed in Duende.AccessTokenManagement.OpenIdConnect 3.0.1.
