What it is

⚠️ A batch feature in Leanote Desktop is the culprit here, mishandling note titles and opening the door for XSS! Think of it like a restaurant accepting orders without checking what's written on the ticket—this means a rogue chef could sneak in a dangerous ingredient that ends up on everyone's plate! 🍽️ An attacker could exploit this flaw to inject malicious code, leading to remote code execution. This is serious, as it could allow attackers to take full control of a victim's machine—imagine someone else driving your car without your permission! 🚗💨
