The Ocean Extra plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 2.4.6. This is due to the software allowing users to execute an action that does not properly validate a value before running do_shortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes when WooCommerce is also installed and activated.

Recent years have seen the development of novel techniques that lead to dramatic improvements in test generation and software testing. They now are mature enough to be assembled in a book – even with executable code.
