What it is

🚨 A crafty little trick in WeaselCMS allows code to ride along in a .png file, and it's easier than you might think! Think of it like sneaking a secret message inside a birthday card—you just need to slide it in unnoticed. That's what this vulnerability does; it disguises harmful code in an innocent-looking image file. If exploited, an attacker could execute malicious PHP code on the server without raising any alarms, leading to unauthorized access and control over critical data. This could mean a total compromise of the website, just like a surprise party that ends up being a total takeover!
