Image Slider by Ays- Responsive Slider and Carousel <= 2.7.0 - Cross-Site Request Forgery to Arbitrary Slider Deletion

The Image Slider by Ays- Responsive Slider and Carousel plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.7.0. This is due to missing or incorrect nonce validation on the bulk delete functionality. This makes it possible for unauthenticated attackers to delete arbitrary sliders via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
