Description
The BjornTech Swish for WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data via the connect_swish_service and disconnect_swish_service AJAX actions in all versions up to, and including, 3.7.8. This is due to a missing capability check in the handlers, which only verified a nonce that the plugin prints on every wp-admin page. This makes it possible for authenticated attackers with contributor-level access and above to disconnect the store from the BjornTech Swish service, clearing the stored account UUID and refresh token. If they know the configured merchant number and e-mail address, they can also restart the service connection, which switches the connection type and replaces the account UUID. Either action disrupts the store's Swish payments.
