Ad Inserter 2.8.12 - 2.8.18 - Subscriber+ RCE / Stored XSS via Global Custom Fields
The Ad Inserter WordPress plugin before 2.8.19 does not correctly restrict access to one of its settings pages, making it reachable by every logged in user under a configuration its own settings allow, and does not filter the content saved there, allowing users with a role as low as subscriber to store code which is then executed as PHP or served unescaped to site visitors.
