/vulndb/XSS Protection Error
A basic XSS protection mechanism is present in every modern browser. This mechanism is active by default but may be disabled by setting the response header “X-XSS-Protection” to the value “0”.
Without the browser’s built-in XSS Protection an attacker is able to perform XSS attacks with simpler payloads.
Ensure that the X-XSS-Protection header is correctly set to prevent some types of XSS attacks.
