Miggo AIRoot Cause Analysis

The vulnerability stems from the conditional check in CodeVerifierAuthenticator.authenticate() that previously only validated if the client required PKCE (isRequireProofKey()), but didn't account for cases where a code_verifier was provided without a corresponding code_challenge. The patch added an additional check (StringUtils.hasText(codeVerifier)) to enforce validation when either condition is true. The commit diff shows this logic change in line 99-100 of CodeVerifierAuthenticator.java, and the added test case in OAuth2AuthorizationCodeGrantTests.java confirms the attack scenario involves providing code_verifier without code_challenge for confidential clients.
