Summary

A significant number of websites, approximately 73-84%, are impacted by jQuery cross-site scripting (XSS) vulnerabilities due to its widespread usage and long-standing presence in web development. This is particularly concerning as the most commonly used version, v1.x, accounts for a large market share, making it potentially vulnerable to exploitation if not properly secured. The majority of known security vulnerabilities affecting jQuery are related to cross-site scripting issues, with some malicious packages also being identified, highlighting the importance of software composition analysis and regular updates to prevent such vulnerabilities from affecting web applications.
