HikaShop (com_hikashop) below 6.8.1 - Unauthenticated Download of Secure Upload Folder Files, Including Purchased Product Files
HikaShop (Starter, Essential and Business) before 6.8.1 lets a visitor download any file in the secure upload folder, including the files customers pay for, without buying it. The frontend download check only compared the requested file name with the value saved in one of the visitor's own custom fields, and did not check that the field was an upload field, so a visitor could type a file name into a text field such as a cart item engraving or an address name and then download that file. The visitor needs to know the file name; no login is needed. Fixed in 6.8.1 (5 November 2026), which refuses frontend downloads through any field that is not a file or image upload field; 6.8.0, released the same day, also fixed an undescribed security issue with downloadable files. No CVE has been published; severity is the mySites.guru CVSS 4.0 assessment (8.2, AV:N/AC:L/AT:P/PR:N/UI:N/VC:H). Update HikaShop to 6.8.1 or later.
Affected versions: < 6.8.1
