Description
The SellKit plugin for WordPress is vulnerable to Blind Server-Side Request Forgery via the Webhook after-submit action of the Opt-in form (Elementor widget and block) in all versions up to, and including, 2.8.0. This is due to the webhook URL being taken from the form settings and requested with wp_remote_post() without restricting the destination. Also, the form submission handlers load the form settings from any post ID, including unpublished drafts. This makes it possible for authenticated attackers, with Contributor-level access and above, to make web requests from the web application to arbitrary locations, including internal services.
