Summary
The WC Product Table Lite plugin for WordPress up to version 5.6.0 is vulnerable to CSS Injection via the 'laptop_scroll_offset' shortcode attribute exposed through the unauthenticated AJAX handler. Lack of value validation and CSS escaping allows unauthenticated attackers to inject arbitrary CSS rules, leading to data exfiltration, UI redressing, and phishing.
Risk Assessment
The organization may face user data exfiltration through CSS-based attacks and UI manipulation. The vulnerability can be exploited without authentication.
Recommendation
Update the WC Product Table Lite plugin to the latest version. Limit sticky sidebar usage and monitor traffic on product table pages.
Original NVD description (English source)
The WC Product Table Lite plugin for WordPress is vulnerable to CSS Injection in versions up to, and including, 5.6.0 via the 'laptop_scroll_offset' shortcode attribute exposed through the unauthenticated wcpt_ajax() AJAX handler. The handler is registered for wp_ajax_nopriv_wcpt_ajax, JSON-decodes attacker-supplied attributes, only allowlists key names (not values), applies a preg_replace that strips only [ ] < >, and passes the value through do_shortcode into wcpt_style__sticky_sidebar(), where it is interpolated verbatim into inline CSS ('top: {$top}px;' and 'max-height: calc(100vh - {$top}px);') with no numeric casting or CSS escaping. This makes it possible for unauthenticated attackers to inject arbitrary CSS declarations and rules on pages rendering a product table with sticky sidebar enabled, which can be leveraged for data exfiltration (via attribute-selector + background-image URLs), UI redressing, and phishing that bypasses CSPs permitting inline styles.
