⚡ An unauthenticated attacker can inject Javascript into customer names! The Kadence WooCommerce Email Designer plugin for WordPress has a serious lapse in input sanitization, putting users at risk! 🔥 Think of it like a restaurant allowing customers to write whatever they want on the reservation list. If the staff doesn't check it, a prankster could slip in a joke that plays when someone tries to verify their reservation — a hidden script that wreaks havoc! This Stored Cross-Site Scripting (XSS) vulnerability means that whenever a user visits a page with an injected name, their browser could execute arbitrary scripts! An attacker could steal cookies or session data, hijack sessions, and perform actions on behalf of users, leading to a complete breach of confidence. Absolutely devastating!
