Injection Guard <= 1.2.1 - Cross-Site Request Forgery via ig_update
The Injection Guard plugin for WordPress is vulnerable to Cross-Site Request Forgery due to a missing nonce check on the ig_update functions in versions up to, and including, 1.2.1. This makes it possible for unauthenticated attackers to make changes to IP block- and allowlists via a forged request granted they can trick an admin into performing an action such as clicking on a link.
