Unauthenticated Arbitrary File Upload in Amasty Order Attributes for Magento 2
CVE-2026-53787 affects Amasty Order Attributes for Magento 2 before version 4.0.0. The vulnerability is an unauthenticated arbitrary file upload flaw in the product's upload endpoint. The endpoint accepts files of any type or name and does not enforce authentication, session validation, or cart context, allowing remote attackers to write arbitrary files into the store's media directory. The available reporting further indicates that the flaw may also permit path traversal, enabling writes outside the intended upload directory. Where the Magento media directory or a reachable written path permits PHP execution, an attacker can upload a PHP payload and achieve remote code execution. Even without PHP execution, the flaw can be abused to host malicious content or to plant HTML/SVG content for stored cross-site scripting.
