Carousel, Slider, Gallery by WP Carousel – Image Carousel & Photo Gallery, Post Carousel & Post Grid, Product Carousel & Product Grid for WooCommerce <= 2.6.3 - Authenticated (Admin+) PHP Object Injection

The plugin is vulnerable to PHP Object Injection in versions up to and including, 2.6.3 via deserialization of untrusted input in the import function via the 'shortcode' parameter. This allows authenticated attackers, with administrator-level access to inject a PHP Object. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.

An attacker needs Admin access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Carousel, Slider, Photo Gallery with Lightbox, Video Slider, by WP Carousel 2.6.4 closes this, and updating the plugin is the step that ends it.
