/vulndb/XSS Protection Disabled
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.
The web application should never explicitly disable the XSS filter.
