This means they could take control of your server, access sensitive data, and wreak havoc on your website — absolutely devastating! 😱
Think of it as a delivery driver bringing in packages without checking the contents — if the driver doesn't inspect the box, an attacker can sneak in a malicious file disguised as a harmless zip file. 📦 The vulnerability lies in the CleanTalk plugin's checkUploadedArchive() function, which allows unauthenticated users to upload and extract .zip archives without proper validation.
