Cloudflare WAF 更新：新增 SharePoint RCE 与 Rails 漏洞规则
WAF - WAF Release - 2026-08-04
推荐理由
WAF 用户需关注：新增的 SharePoint RCE 和 Rails 漏洞规则已设为 Block，且 SSRF 云防护默认阻断，建议及时更新托管规则集以抵御这些攻击。
This release introduces new rules and updates Microsoft SharePoint RCE alongside enhanced SSRF cloud protection rule actions.
Key Findings
- CVE-2026-50522: An insecure deserialization vulnerability in Microsoft SharePoint Server. This may allow an unauthenticated attacker to execute arbitrary code using crafted requests.
- CVE-2026-66066: An improper input processing vulnerability in Ruby on Rails Active Storage image variant transformations. This may allow an unauthenticated attacker to perform arbitrary file reads and achieve Remote Code Execution (RCE) using maliciously crafted payload requests.
- Generic Cloud Protections: Added improved detection logic targeting Server-Side Request Forgery (SSRF) in cloud-hosted applications.
