False positive Java. SpringBoot CSRF

まず、"Disabled Spring CSRF protection" という名前の CodeQL クエリを見つけ、Spring Security 構成をどのように識別しているかを確認します。次に、提供された stateless JWT/OIDC resource-server の例を再現し、この構成で CSRF を無効にしてもクエリがトリガーされなくなり、報告されたケースは引き続きカバーされることを検証します。

Description of the false positive

Given a SpringBoot application that acts solely as an API/OIDC Resource Server and does not utilize cookies or state, where CSRF is disabled, the CodeQL / Disabled Spring CSRF protection should not be triggered.
