description: Cloudflare WAF managed rulesets 2025-09-26 release

import { RuleID } from "~/components";

**Managed Ruleset Updated**

This update introduces 11 new detections in the Cloudflare Managed Ruleset (all currently set to Disabled mode to preserve remediation logic and allow quick activation if needed). The rules cover a broad spectrum of threats - SQL injection techniques, command and code injection, information disclosure of common files, URL anomalies, and cross-site scripting.
