OVERVIEW

Unused authorization codes issued to deleted users can still be used to obtain access tokens.

DESCRIPTION

Unused authorization codes issued to deleted users are not being removed. This allows malicious actors to claim access tokens on behalf of already deleted users.

IMPACT

Since unused authorization codes for deleted users are not removed a malicious actor could be able to claim access tokens on their behalf. This is possible only if the malicious actor has access to the authorization code client ID and the client secret. Given the above conditions are met this may lead to unauthorized access to sensitive resources and services depending on scopes authorized for the authorization code.
