“…The most widespread flaw in web applications is the injection, which includes SQL, HTML, CRLF, and other types of injection. Other flaws include XSS, broken access control, security misconfiguration, exposed sensitive data, inadequate attack protection, using components with known vulnerabilities, using unprotected APIs, local file inclusion, and broken authentication and session management [1] [7]. To solve this problem, many researchers have tried several methods but less research has been carried out in the area of CRLF vulnerability detection or discovery, and this still remains one of the most critical vulnerabilities.…”
