Nuclei template

The nuclei engine has its limitations, but with some pipe hacks and jq, one can scan a list of targets. It will result in a ton of false positives but will be much faster. See the template and usage:

$ chaos -d u**r.com -bbq -http-url --silent | nuclei -t wp-update-confusion.yaml -json | jq -r '"https://plugins.svn.wordpress.org/" + .["extracted-results"][] + "/?" + .["matched-at"]' | httpx -silent -random-agent -mc 404
