- Simple Explanation: A type of security vulnerability where malicious code is injected into a trusted website, potentially allowing an attacker to steal sensitive information or perform unauthorized actions.
- Example: An attacker inserting a script into a website’s input field that executes when other users view the page, potentially stealing their login credentials.
- Advanced Explanation: A web security vulnerability that occurs when a website allows user-supplied data to be included in web pages without proper validation or encoding, enabling attackers to inject and execute malicious scripts in users’ browsers.
