Stored cross-site scripting via unescaped admin settings
Published Aug 31, 2023 · Updated Apr 8, 2026
Stored XSS in WooCommerce PDF Invoice Builder 1.2.90 and earlier allows remote authenticated users to inject scripts through admin settings. The admin settings path in woocommerce-pdf-invoice-ajax.php stores input without sufficient sanitization and later emits it without output escaping. Administrator privileges are required, and exposure is limited to multisite installations or sites with unfiltered_html disabled; the script runs when a user opens the affected page.
