Cloudflare WAF 更新：新增 Nuxt RCE 与 Fastjson 防护
WAF - WAF Release - 2026-07-29
推荐理由
Cloudflare WAF 用户需关注：新增规则直接阻断高危 RCE 与 SSRF 攻击，建议尽快确认托管规则集已自动启用，并检查自定义配置是否覆盖。
This release introduces new rules and updates existing threat signatures to provide targeted protections for vulnerabilities in Nuxt Server Island components and Alibaba Fastjson deserialization routines, alongside enhanced protections for cloud metadata Server-Side Request Forgery (SSRF) and obfuscated command injection attempts.
Key Findings
- Nuxt Server Island - RCE(GHSA-9473-5f9j-94wq): An unauthenticated vulnerability in Nuxt Server Islands where remote attackers can supply arbitrary component names or props to endpoints. Manipulating these parameters allows unauthenticated component Remote Code Execution (RCE) on the server.
- Alibaba Fastjson JSONType Remote Code Execution: A unauthenticated remote code execution vulnerability in Alibaba Fastjson (≤ 1.2.83) during JSON deserialization. Under default configurations, attackers can execute arbitrary system commands, bypassing traditional classpath and gadget-based defenses.
- Generic Protections (SSRF & Command Injection): Added improved detection logic targeting Server-Side Request Forgery (SSRF) in cloud-hosted applications, alongside new rules targeting obfuscated command injection patterns across request parameters.
