Think of it like a restaurant menu that allows customers to add their own items. If no one checks what’s added, a mischievous diner could sneak in a dish that sets off a food fight in the kitchen! The vulnerability results from improper sanitization of web app properties, allowing bad actors to inject dangerous commands into XDG Desktop Entries and `AppInfo.ini` files on Linux and PortableApps.com systems. This means that an attacker can define executable commands that run when their malicious web app is launched.
