'''HTTP header injection''' is a general class of [[web application]] [[security vulnerability]] which occurs when [[Hypertext Transfer Protocol]] ([[HTTP]]) [[list of HTTP headers|headers]] are dynamically generated based on user input. [[Header (computing)|Header]] injection in HTTP responses can allow for [[HTTP response splitting]], and[[session fixation]] via the Set-[[CrossHTTP cookie|Cookie]] header, [[cross-site scripting]] (XSS), and malicious redirect attacks via the ___location header. [[XSS]] attacks can be blocked with the use of an [[Browser extension|extension]] such as [[NoScript]] or Malwarebytes Browser Guard on your [[Web browser|browser]].
