Name of the Vulnerable Software and Affected Versions UmbracoIdentityExtensions versions (affected versions not specified)

Description The issue concerns the UmbracoIdentityExtensions package, which is an Umbraco add-on for ASP.Net Identity integration. In affected versions, client secrets are not required, potentially exposing some endpoints to untrusted actors. Since Umbraco is not a single-page application, the implicit flow is not safe. For traditional MVC applications, it is recommended to use the authorization code flow, which requires the client to authenticate with the authorization server using a client secret. This flow provides better security, as it involves exchanging an authorization code for an access token and/or ID token, rather than directly returning tokens in the URL fragment.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
