Fail2ban action.d for Cloudflare meant to replace the version that ships with fail2ban currently. This updated version of the action uses Cloudflare's 2023 v4 API (free tier WAF + free tier WAF lists) to ban hostile IPs.

| # This version works with CF WAF (using zone rulesets) and obsoletes previous | |
| # versions. This works will all CF account types. This action depends on curl | |
| # and jp and will add/remove IPs from the $known_hostile_ips list. Creating the | |
| # WAF rules need only be done once per zone. Creating the list need only be done | |
| # once per account. | |
