{"id":"CVE-2026-15441","state":"PUBLISHED","title":"Product Table & List Builder For WooCommerce <= 5.6.0 - Unauthenticated CSS Injection via 'laptop_scroll_offset' Parameter","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.","publishedAt":"2026-08-16T04:24:53.729Z","updatedAt":"2026-08-18T19:18:37.400Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["wcproducttable Product Table & List Builder For WooCommerce"],"affected":[{"vendor":"wcproducttable","product":"Product Table & List Builder For WooCommerce","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"5.6.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/6c0a8be1-8853-4863-90e5-af3831f800e9?source=cve","https://plugins.trac.wordpress.org/browser/wc-product-table-lite/tags/5.4.0/style-functions.php#L995","https://plugins.trac.wordpress.org/browser/wc-product-table-lite/tags/5.4.0/main.php#L2677","https://plugins.trac.wordpress.org/browser/wc-product-table-lite/tags/5.4.0/main.php#L2686","https://plugins.trac.wordpress.org/browser/wc-product-table-lite/tags/5.1.0/style-functions.php#L995","https://plugins.trac.wordpress.org/browser/wc-product-table-lite/tags/5.1.0/main.php#L2677","https://plugins.trac.wordpress.org/browser/wc-product-table-lite/tags/5.1.0/main.php#L2686","https://plugins.trac.wordpress.org/changeset?reponame=&old=3638932%40wc-product-table-lite&new=3638932%40wc-product-table-lite"],"weaknesses":["CWE-74"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/15xxx/CVE-2026-15441.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-15441","state":"PUBLISHED","datePublished":"2026-08-16T04:24:53.729Z","dateUpdated":"2026-08-18T19:18:37.400Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-07-10T19:06:47.337Z"},"containers":{"cna":{"title":"Product Table & List Builder For WooCommerce <= 5.6.0 - Unauthenticated CSS Injection via 'laptop_scroll_offset' Parameter","descriptions":[{"lang":"en","value":"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.
