CVE-2023-48228
Date: November 21, 2023
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.
