The JTL-Connector for WooCommerce plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 2.4.3 via the saveImage() function. This is due to the startSession() function accepting an empty jtlauth parameter as a valid credential, combined with insufficient file type validation in handleImagePush(). This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible.
