Description

The OneSignal – Web Push Notifications plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the settings handling functionality in all versions up to, and including, 3.6.1. This is due to the plugin processing POST requests without verifying user capabilities or nonces. This makes it possible for unauthenticated attackers to overwrite the OneSignal App ID, REST API key, and notification behavior via direct POST requests.
