CVE-2026-112044 Details
Description
A security vulnerability has been detected in dotnet eShop up to 913acea66708a59595351174cee9b29f37179d29. The affected element is the function AddApplicationServices of the file src/Catalog.API/Extensions/Extensions.cs of the component Catalog API. The manipulation leads to improper authentication. The attack can be initiated remotely. The project was informed of the problem early through an issue report but has not responded yet.
A vulnerability allowing improper authentication has been identified in the dotnet eShop Catalog API, in versions prior to commit 913acea66708a59595351174cee9b29f37179d29. The issue arises in the AddApplicationServices function within src/Catalog.API/Extensions/Extensions.cs. This vulnerability allows unauthenticated network clients to create, update, or delete catalog items remotely, bypassing authentication and authorization requirements. The problem was reported to the project, but no response has been received.
The vulnerability can be addressed by adding authentication and authorization to the Catalog API's mutation endpoints. This involves calling 'builder.AddDefaultAuthentication()' in the Extensions.cs file, enabling 'UseAuthentication()' and 'UseAuthorization()' in the Program.cs, and applying '.RequireAuthorization()' to the mutation routes. Additionally, the Catalog API resource should be configured to receive 'Identity__Url' in the AppHost.
