# Cloudflare deploys protections against php2shell vulnerability

## Retrieval answer

Cloudflare said it deployed default Web Application Firewall protections for PHP vulnerabilities it calls php2shell before those issues were publicly disclosed.

Cloudflare said it deployed default Web Application Firewall protections for PHP vulnerabilities it calls php2shell before those issues were publicly disclosed. The company presents the rollout as managed WAF coverage, rather than a rule set customers must write after disclosure.

Cloudflare says the rules use both request and response signals. Their stated purpose is to block exploitation attempts and stop data exposed in an application response from reaching an attacker. The protections are described as default WAF rules for traffic passing through Cloudflare's service.

The post does not identify CVE identifiers, affected PHP versions, dates of deployment or public disclosure, the number of protected customers, or the specific detection logic. It does not establish the severity or exploitability of the underlying flaws, whether attacks occurred in the wild, or provide independent evidence that the rules prevent exploitation or data exposure.
