Shopper 管理面板漏洞 CVE-2026-62990 允許執行指令碼與持久化建立管理員帳號
CVE-2026-62990 - Shopper: same-origin SVG and HTML uploads enable stored XSS and persistent administrator creation
Shopper 的 Headless 電商管理面板在 2.x 與 3.x 早期版本中存在同源 SVG/HTML 上傳漏洞，攻擊者可透過執行指令碼取得管理員許可權並持久化建立新管理員帳號。
此漏洞允許攻擊者在管理員存取時執行指令碼，造成管理許可權被奪取，提醒使用者即時升級以防止資料外洩，以確保商業資料安全。
Shopper is a Headless e-commerce Admin Panel. In versions from 2.0.0 prior to 2.10.1 and in the 3.0.0 prereleases beta.1 and beta.2, authenticated back-office staff with a content-upload permission can store executable media on the administrator's own origin. In the 2.x implementation, relevant upload permissions include `edit_products` or `add_brands`, and `packages/admin/config/media.php` allows `image/svg+xml` in every media collection, including image fields whose image/* validation also accepts SVG. The product files collection in `packages/admin/src/Livewire/Components/Products/Form/Files.php` has no MIME restriction and accepts `text/html` as well. Media is served inline from the `public` disk under `/storage/` with its own content type, without `Content-Disposition: attachment` or a `Content-Security-Policy`. When an administrator opens an uploaded HTML or SVG file, stored script executes in that administrator's session. In 2.x, the script can invoke `packages/admin/src/Livewire/SlideOvers/CreateTeamMember.php`, whose `store()` checks `access_setting` held by the viewing administrator but trusts client-supplied `role_id`, to create a new attacker-controlled administrator with a chosen password. This account persists after the uploaded file is deleted and gives access to customer data, orders, settings, and user/role management; the same script can exfiltrate data or grant permissions to the attacker's account. Direct account creation by the low-privileged uploader is blocked, so exploitation requires the administrator to open the file. The 3.x prerelease line already excludes SVG but still allows executable product files. This issue is fixed in versions 2.10.1 and 3.0.0-beta.3.
