What to do
Solution: To mitigate this vulnerability, implement output encoding to prevent malicious script injection in user-controlled input fields, ensure that session cookies are set with the HttpOnly and Secure flags to protect them from client-side access, and validate and sanitize user input before reflecting it in web pages.
