⚡ An improper input handling flaw lets attackers execute arbitrary JavaScript! This Reflected XSS vulnerability in Matamko En Masse could turn any click into a potential disaster. 🔥 Think of it like a restaurant that accepts orders without checking the ingredients. An attacker can sneak in their own special recipe, serving up malicious code instead of the intended dish — and all your guests could end up with a sour stomach!
