Versions of keystone prior to 4.0.0 are vulnerable to Cross-Site Scripting (XSS). The package fails to sanitize user input on the Contact Us page, allowing attackers to submit contact forms with malicious JavaScript in the message field. The output is not properly encoded leading an admin that opens new inquiry to execute the arbitrary JavaScript supplied in their browser.

Recommendation

Update to version 4.0.0 or later.
