Technical details

The plugin fails to sanitize and escape the 'woosq-redirect' parameter, allowing unauthenticated reflected XSS. The vulnerability is triggered when the WooCommerce "redirect to cart after add to cart" option is enabled and a user loads a crafted URL containing the malicious payload in the woosq-redirect parameter; the ?quick-view= parameter causes automatic execution without further user interaction beyond clicking the link.
