CyberRota Analysis
AI-GeneratedThe WC Product Table Lite plugin for WordPress is vulnerable to CSS Injection due to improper handling of the 'laptop_scroll_offset' shortcode attribute in versions up to 5.6.0. This flaw allows unauthenticated attackers to inject arbitrary CSS, potentially leading to data exfiltration, UI redressing, and phishing attacks that can circumvent Content Security Policies. WordPress site administrators using this plugin should prioritize patching to mitigate these risks.
Original NVD Description
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.
