                               [--wait-time WAIT_TIME] [--waf-bypass] [--test-CVE-2021-45046] [--server SERVER]

  -c CRAW, --crawler CRAW
                        use crawler,any values,like 1
  -p PROXY, --proxy PROXY

  --exclude-user-agent-fuzzing
                        Exclude User-Agent header from fuzzing - useful to bypass weak checks on User-Agents.
