Guest return-label disclosure via missing permission check
Published Jul 23, 2026 · Updated Jul 23, 2026
Authorization bypass in vendidero Shiptastic for WooCommerce 5.1.0 and earlier allows remote attackers to download guest-order return labels. The guest-order return-label download path performs no proper permission check before returning a label, allowing the requested object to be fetched outside an authorized session. No account is required, and the bounded consequence is disclosure of return-label files associated with guest orders rather than modification of orders or store data.
