This vulnerability lurks in the PostGuestbook 0.6.1 module for PHP-Nuke, and it’s absolutely worth your attention! 🔍 Think of it as a restaurant that lets you bring your own ingredients for the chef to cook with, but the chef doesn't check what you're providing — if someone sneaks in spoiled food, the dish could turn toxic!
