🚨 Users can turn their profiles into script-launching pads! An attacker with the ability to edit their own profile can execute arbitrary Groovy and Python scripts—total chaos! 🔥 Think of it like giving a guest full access to the kitchen: if they can cook whatever they want, they might just whip up a recipe for disaster, serving up malicious code instead of a nice meal! 🍽️ If exploited, this vulnerability allows attackers to execute remote code, granting them unrestricted access to all wiki contents. Imagine a hacker walking in and rummaging through your entire pantry—data leaks, unauthorized changes, and even complete takeover could happen. This is a nightmare scenario for any organization relying on XWiki!
