CVE-2026-15441Network attack vector

Unauthenticated UI redressing via unescaped CSS value

Published Aug 16, 2026 · Updated Aug 16, 2026

CSS injection in Product Table & List Builder for WooCommerce 5.6.0 and earlier allows remote attackers to alter page styles via AJAX. The unauthenticated wcpt_ajax() handler JSON-decodes shortcode attributes, filters only attribute names, strips only square and angle brackets, and inserts laptop_scroll_offset verbatim into inline top and max-height declarations. Exposure requires a rendered product table with sticky sidebar enabled; the bounded impact is UI redressing and phishing, while CSS data exfiltration depends on page content and browser behavior.
