{"id":"CVE-2024-51987","state":"PUBLISHED","title":"HTTP Client uses incorrect token after refresh in Duende.AccessTokenManagement.OpenIdConnect","description":"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.","publishedAt":"2024-11-07T23:36:16.989Z","updatedAt":"2024-11-08T15:57:51.304Z","severity":{"score":5.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["DuendeSoftware Duende.AccessTokenManagement"],"affected":[{"vendor":"DuendeSoftware","product":"Duende.AccessTokenManagement","versions":[{"version":"= 3.0.0","status":"affected"}]}],"references":["https://github.com/DuendeSoftware/Duende.AccessTokenManagement/security/advisories/GHSA-7mr7-4f54-vcx5"],"weaknesses":["CWE-270"],"ingestedAt":"2026-10-29T20:08:04.920Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2024/51xxx/CVE-2024-51987.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2024-51987","state":"PUBLISHED","datePublished":"2024-11-07T23:36:16.989Z","dateUpdated":"2024-11-08T15:57:51.304Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2024-11-04T17:46:16.774Z"},"containers":{"cna":{"title":"HTTP Client uses incorrect token after refresh in Duende.AccessTokenManagement.OpenIdConnect","descriptions":[{"lang":"en","value":"Duende.AccessTokenManagement.OpenIdConnect is a set of .NET libraries that manage OAuth and OpenId Connect access tokens.
