⚠️ A crafty double-extension upload is the sneaky trick here! The WooCommerce Upload Files plugin let’s you bypass file type restrictions like a magician pulling a rabbit out of a hat. 🎩 Think of it like a restaurant that only allows certain dishes, but someone cleverly orders a dish by disguising it as a special. If the kitchen isn't paying attention, that 'special' could very well be a forbidden recipe! An attacker could upload malicious PHP files disguised as safe uploads, which could lead to remote code execution and a complete compromise of the site. This means your website could become a playground for attackers, potentially leaking sensitive customer data or paving the way for further exploits.
