Cross Site Scripting (XSS)

Cross-Site Scripting (XSS) refers to a security vulnerability in web applications where an attacker injects malicious scripts into content delivered to users. These scripts are executed in the user's browser without their knowledge, allowing the attacker to steal sensitive data. In the context of online fundraising, XSS could be used to display a look-alike donation form on your website, enabling attackers to steal donor information or divert donations to fraudulent accounts. XSS vulnerabilities typically occur when a web application fails to properly validate or sanitize user input before displaying it on a webpage. To mitigate XSS risks, developers should implement input validation, encode outputs, regularly update their web technology, and use security features like Content Security Policy (CSP).
