Accepted Answer

What is Stored Cross-Site Scripting (XSS)?

Stored Cross-Site Scripting (XSS) is a type of security vulnerability where an attacker injects malicious scripts into a web application, which are then stored on the server. When other users access the compromised pages, the malicious scripts execute within their browsers. This can lead to a range of issues, from minor nuisances to significant security breaches, including data theft, session hijacking, and the spread of malware.

Stored XSS vulnerabilities are particularly dangerous because the injected scripts are saved by the server and can affect multiple users over time, making them a critical target for remediation in web applications.
