PKCE support is not implemented in accordance with the RFC for OAuth 2.0 for Native Apps. Without the use of PKCE, the authorization code returned by an authorization server is not enough to guarantee that the client that issued the initial authorization request is the one that will be authorized. An attacker is able to obtain the authorization code using a malicious app on the client-side and use it to gain authorization to the protected resource. This affects the package com.google.oauth-client:google-oauth-client before 1.31.0.

Marking Red Hat Fuse 7 as having a lower impact (low) than that of the base flaw (important), this is because it ships and uses a vulnerable version of google-oauth-client as part of camel-google-calendar, camel-google-drive and camel-google-mail camel components but crucially does not use the potentially vulnerable Authorization Code flow (without PKCE), this means the steps for which PKCE is relevant are not handled by Fuse
