Reflected XSS via unescaped failed_orders admin notice

Published May 14, 2026 · Updated May 14, 2026

Reflected XSS in GLS Shipping for WooCommerce 1.4.0 and earlier allows remote attackers to execute scripts via failed_orders. The bulk-action admin notice reads failed_orders without adequate sanitization and renders its values without output escaping. Exploitation requires a user to follow a crafted link, after which the payload runs in that user's browser under the WordPress site's origin.
