EWWW Image Optimizer <= 5.8.1 - Cross-Site Request Forgery Bypass

The EWWW Image Optimizer plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 5.8.1. This is due to missing or incorrect nonce validation on the ewww_ngg_bulk_init() function. This makes it possible for unauthenticated attackers to perform bulk image optimization via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

EWWW Image Optimizer before 2.8.5 allows remote command execution because it relies on a protection mechanism involving boolval, which is unavailable before PHP 5.5.
