Put simply

Think of it like a restaurant kitchen where a rogue chef can secretly add a nasty ingredient to every dish served to customers—every unsuspecting diner suffers from it! This XSS vulnerability arises from improper input handling during web page generation in Hotech's Otello software, allowing attackers to store harmful scripts on the server, which then execute in users' browsers.

This could lead to stolen session cookies, redirected traffic, or even defaced content—absolutely devastating for your users' trust and your brand's reputation! To protect your users, update Otello to version 2.4.4 or later immediately.
