⚡ A missing file type validation is the key flaw here! The Featured Image via URL plugin for WordPress allows authenticated attackers to upload any file they want, creating a huge risk! 🔥 Think of it like a hotel that lets guests drop off any package at the front desk without checking what’s inside. A guest could send a dangerous item right into the building without anyone noticing! An attacker at Contributor-level access could upload malicious files that can lead to remote code execution on the server. This could result in complete control over the website, allowing them to steal sensitive data, alter content, or even bring the site down completely!
