⚡ A crafty XSS vulnerability lurks in GitHub's answerdev/answer before version 1.0.4! An attacker can inject malicious scripts into otherwise trusted pages, just waiting for a user to take the bait! Think of this as a restaurant server who accepts a hidden note from a customer — instead of checking it, they just deliver it straight to the kitchen without questioning what's in it. That note can contain all sorts of mischievous instructions! If exploited, a bad actor could execute arbitrary scripts in users' browsers, leading to data theft or unauthorized actions. This vulnerability could turn a friendly chat into an all-out hack-fest, letting attackers steal cookies, sessions, or even personal information — absolutely devastating!
