What is Stored Cross-Site Scripting (XSS)?

Stored Cross-Site Scripting, or XSS, is a web security vulnerability that allows attackers to inject malicious scripts into web pages viewed by other users. Unlike reflected XSS, which requires a user to actively trigger the attack, stored XSS persists on the web server and affects users who access the compromised page, making it particularly dangerous.

This type of vulnerability can lead to various security issues, including unauthorized access to user data, session hijacking, and website defacement. Ensuring input sanitization and validation is a key defense against stored XSS attacks.
