EWWW Image Optimizer < 7.3.0 - Cross-Site Request Forgery

Description The EWWW Image Optimizer plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 7.2.3. This is due to missing or incorrect nonce validation on the check_for_optin() and check_for_optout() functions. This makes it possible for unauthenticated attackers to opt in and out of tracking via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
