CWE CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
OWASP A07:2017 - Cross-Site Scripting (XSS)
Confidence Level Medium
Impact Level Medium
Likelihood Level Medium

Description

User input from the browser's location (such as URL parameters or fragments) is being directly inserted into HTML strings without proper sanitization. This can allow attackers to inject malicious scripts into the page.

Impact

If exploited, attackers could execute arbitrary JavaScript in users' browsers (XSS), leading to stolen data, account compromise, or unauthorized actions on behalf of users. This threatens user safety and can damage trust in the application.
