🚨 A single malicious URL could unleash chaos in your browser! The Tarkov Data Manager's toast notification system has a critical XSS vulnerability that lets attackers execute arbitrary JavaScript in user sessions. 🔥 Think of it as a restaurant that serves up a special notification on the menu, but the chef accidentally includes a recipe for disaster — anyone can swap in a harmful ingredient that ruins the entire dining experience! If exploited, an attacker could hijack a victim’s session, stealing sensitive information or performing actions on their behalf, all while masquerading as the victim themselves. This could lead to unauthorized access to accounts, data leaks, or worse!
