🚨 A crafty edit could let any user with basic access execute code on your server! This vulnerability in XWiki is alarmingly easy to exploit. 🔥 Think of it like a hotel where guests can write their own room service menu. If one guest decides to order something dangerous, it gets served up to the whole establishment! An attacker could sneak in some malicious Groovy script and execute it on the server, leading to full remote code execution. This means they could access data, modify configurations, or even take over the entire server—absolutely devastating!
