Joomla Extension - j2commerce.com - Unauthenticated file upload with missing directory protection in J2Store 1.0.0-3.3.20, 4.0.0-4.0.20, 4.1.0-4.1.5 - The file upload endpoint accepted POST requests from unauthenticated visitors with no CSRF token. Compounding this, the installer manifest omitted the upload and invoices directories, causing fresh installs to deploy those directories without .htaccess/web.config protection, making uploaded files directly web-accessible.
