Technical details
The vulnerability exists within the OAuth Handler and dashboard modules of django-jet up to version 1.0.8. Specifically, the Google Analytics and Yandex Metrika credential revoke endpoints lack authentication, ownership checks, and CSRF protection. Additionally, the OAuth flow uses the module's primary key as the 'state' parameter instead of a cryptographically secure nonce, allowing an attacker to bind a victim's third-party authorization to an attacker-controlled module. Attackers can exploit these flaws remotely by inducing a logged-in staff user to visit a malicious URL. As of the advisory date, the project has not released a patch.
