SCA: security update for Duende.IdentityServer (GHSA-v9xq-2mvm-x8xc)

low Tenable Self-Hosted Container Security Plugin ID 419246

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Duende IdentityServer is an OpenID Connect and OAuth 2.x framework for ASP.NET Core. IdentityServer's
 local API authentication handler performs insufficient validation of the cnf claim in DPoP access tokens.
 This allows an attacker to use leaked DPoP access tokens at local api endpoints even without possessing
 the private key for signing proof tokens. Note that this only impacts custom endpoints within an
 IdentityServer implementation that have explicitly used the LocalApiAuthenticationHandler for
 authentication. This vulnerability is patched in IdentityServer 7.0.8. Version 6.3 and below are
 unaffected, as they do not support DPoP in Local APIs. (CVE-2024-49755)
