Cross-Site Scripting, or XSS, is a security vulnerability in web applications that allows criminal hackers to inject harmful code directly inside web pages. This can result in a massive data breach, as seen in 2018 when the private data (including payment information) of 380,000 British Airways customers was stolen by attackers.
