CVE-2024-51987 (GCVE-0-2024-51987)

Vulnerability from cvelistv5 – Published: 2024-11-07 23:36 – Updated: 2024-11-08 15:57

Title

HTTP Client uses incorrect token after refresh in Duende.AccessTokenManagement.OpenIdConnect

Summary

Duende.AccessTokenManagement.OpenIdConnect is a set of .NET libraries that manage OAuth and OpenId Connect access tokens. HTTP Clients created by `AddUserAccessTokenHttpClient` may use a different user's access token after a token refresh occurs. This occurs because a refreshed token will be captured in pooled `HttpClient` instances, which may be used by a different user. 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. This issue is fixed in Duende.AccessTokenManagement.OpenIdConnect 3.0.1. All users are advised to upgrade. There are no known workarounds for this vulnerability.

GHSA-7MR7-4F54-VCX5

Vulnerability from github – Published: 2024-11-07 21:57 – Updated: 2024-11-08 13:55

Summary

HTTP Client uses incorrect token after refresh

Details

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.
