Плагин просто великолепный. В планах приобрести лицензию, но смущает давние обновления, не перестанут ли поддерживать данный плагин! Есть конечно вопросы по работе и возможности их корректировать.Допустим при использовании плагина woo-invoices все отлично формируется и работает. Но в описании товара при заказе с атрибутами выводятся не описания атрибута ( Количество ), а его ярлык ( attributes_quantity_size ).

  • FIX: restrict access to sending emails to Adminstrator users only (thanks to Patchstack). NOTE: Patchstack reported a vulnerability where existing users of any role could abuse an AJAX URL to send emails through Sliced Invoices. To exploit this, the attacker would have to already have access to an existing user account and be logged in to do so — no access was open to the general public. Please note this is a theoretical vulnerability only — we have no reports of any such attacks actually taking place in the real world.

  • UPDATE: add new filters sliced_get_email_headers, and sliced_invoices_non_cloneable_post_metas.

  • FIX: commas incorrectly removed from “To” field in email preview window, whenever multiple email addresses filtered in.
  • FIX: second-order SQL injection vulnerability if an existing meta_key contains unsafe code (thanks to Wordfence). NOTE: to exploit this, an attacker would need to first be logged in as an administator, and be able to insert a specially-crafted post meta containing malicious code. There is no direct danger; this could only happen if someone already had access to your database, or if your site was already compromised by some other means.
