This could result in complete control over your site, allowing data breaches, defacement, or even using your server for malicious activities. We're talking about a real security nightmare!
Think of it like a restaurant that lets anyone drop off a mystery dish in the kitchen without checking what’s in it — that dish could be delicious or downright dangerous! 🍽️ This vulnerability exists in the File Uploader for WooCommerce plugin due to the lack of proper file type validation in the 'add-image-data' REST API endpoint, allowing arbitrary file uploads across all versions up to 1.0.3.
