Overview
About vulnerability
Summary
The C parser (the default for most installs) accepted null bytes and control characters in request headers.
Impact
An attacker could send header values that are interpreted differently than expected due to the presence of control characters. For example, request.url.origin() may return a different value than the raw Host header, or what a reverse proxy interpreted it as., potentially resulting in some kind of security bypass.
