Unauthenticated script execution via unescaped billing fields
Published Oct 1, 2026 · Updated Oct 1, 2026
Stored XSS in WP Overnight PDF Invoices & Packing Slips for WooCommerce 5.16.1 and earlier lets remote attackers run scripts through billing fields. The plugin renders stored billing first-name, last-name, and company values without sufficient output escaping; entity-encoded payloads pass WooCommerce text cleaners when they contain no literal less-than sign. Guest checkout permits unauthenticated order placement, but script execution requires another user to view a page displaying the injected billing data.
