The Notification for Telegram plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.5.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to create, modify, or reschedule the nftb_cron_hook WordPress cron event, enabling unauthorized manipulation of the plugin's background task scheduling logic.
