What it is

⚡ A simple oversight in the FitLine theme lets attackers slip files into your PHP app, like a sneaky delivery that doesn't even require a signature! Imagine a restaurant where anyone can place an order without checking if they’re on the list — that’s how this vulnerability works, allowing unauthorized files to be included in your code. An attacker could exploit this flaw to include arbitrary files from the server, which can lead to unauthorized access or even full control of your application. This could result in devastating data breaches or system compromises. It's a serious risk if left unaddressed!
