JavaScript vulnerability exposes users to cross-site scripting attacks, allowing hackers to inject malicious code into web pages and steal sensitive information. This type of attack can occur when user input is not properly sanitized, enabling attackers to execute arbitrary JavaScript code on a victim's browser. To prevent XSS attacks, developers must validate and sanitize all user input before rendering it in the application, ensuring that only trusted data is displayed to users.
