Drupal discovered a severe vulnerability and said they would release a patch. When the patch was released we analysed and created rules to mitigate these. By analysing the patch we created WAF rules to protect Cloudflare customers running Drupal.
Announcing Firewall Rules
Threat landscapes change every second. As attackers evolve, vulnerabilities materialise faster than engineers can patch systems becoming more dynamic and devious. Part of Cloudflare’s mission is to keep you and your applications safe.
Keeping Drupal sites safe with Cloudflare's WAF
Cloudflare’s team of security analysts monitor for upcoming threats and vulnerabilities and where possible put protection in place for upcoming threats before they compromise our customers.
Cloudflare is adding Drupal WAF Rule to Mitigate Critical Drupal Exploit

From time to time a customer writes in and asks about certain requests that have been blocked by the CloudFlare WAF. Recently, a customer couldn’t understand why it appeared that some simple GET requests for their homepage were listed as blocked in WAF analytics.
