Detailsinfo

A vulnerability, which was classified as problematic, was found in UmbracoIdentityExtensions up to 2.0.0. This affects some unknown functionality. The manipulation with an unknown input leads to a information disclosure vulnerability. CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality. The summary by CVE is:

UmbracoIdentityExtensions is an Umbraco add-on package that enables easy extensibility points for ASP.Net Identity integration. In affected versions client secrets are not required which may expose 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. This issue has been patched in commit `e792429f9` and a release to Nuget is pending. Users are advised to upgrade when possible.

The weakness was disclosed 06/10/2023 as GHSA-f2rf-8mwf-6jfh. The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2023-32312 since 05/08/2023.
