Technical details

The plugin fails to properly sanitize and escape the 'qode_wishlist_for_woocommerce_guests_items' parameter in REST API endpoints, allowing stored cross-site scripting attacks. Unauthenticated attackers can exploit this because the wp_rest nonce is publicly exposed on the /wishlist/ page and they control the transient key where payloads are stored. The vulnerability requires administrative action to fully trigger but can be chained with social engineering to compromise site administrators and users.
