Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-270: Privilege Context Switching Error, where the product does not properly manage privileges while it is switching between different contexts that have different privileges or spheres of control. In Duende.AccessTokenManagement.OpenIdConnect, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### 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.
