Description
The Ona theme for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 1.26 via the ona_activate_child_theme. This makes it possible for authenticated attackers, with administrator-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.
