CVE-2023-48228:
NixOS vulnerability analysis and mitigation
authentik is an open-source identity provider. When initialising a oauth2 flow with a code_challenge and code_method (thus requesting PKCE), the single sign-on provider (authentik) must check if there is a matching and existing code_verifier during the token step. Prior to versions 2023.10.4 and 2023.8.5, authentik checks if the contents of code_verifier is matching only when it is provided. When it is left out completely, authentik simply accepts the token request with out it; even when the flow was started with a code_challenge. authentik 2023.8.5 and 2023.10.4 fix this issue.
