Description
The Casso Flow plugin for WordPress is vulnerable to unauthorized modification of data via the 'oauth2_status' parameter in all versions up to, and including, 4.1.1, due to a missing capability check in the Casso_Admin_Page constructor. The constructor runs disconnectOAuth2() on any request to an admin endpoint (including admin-ajax.php), with no capability check and no nonce. This makes it possible for unauthenticated attackers to disconnect a Casso integration linked through OAuth: they can delete its webhooks, wipe the stored bank accounts and reset the plugin's payment settings.
