セキュリティ監査

v1 • 2026/8/9 バージョン別レポートを開く

All 74 static alerts are false positives caused by Markdown formatting, documented official API calls, Worker handler syntax, or Durable Object SQL APIs. Semantic review found three medium concerns involving untrusted email content, unescaped HTML replies, and sensitive message logging. No malicious prompt injection, credential exfiltration, or arbitrary process execution was found.

references/routing.md:111references/routing.md:145-155
Untrusted Email Content Can Reach an AI Workflow
The guide stores inbound email text and suggests notifying an AI agent to draft replies without defining an untrusted-content boundary. Crafted email text could attempt indirect prompt injection before the agent uses reply capabilities.
The guide explicitly combines stored inbound content with optional AI drafting. The agent call is illustrative and commented, so exploitability depends on the implementation.
中
references/routing.md:166-179
Reply Content Is Inserted Into HTML Without Escaping
The reply example inserts replyBody directly into an HTML template. Untrusted or AI-generated markup could alter outgoing email content or add tracking and phishing elements.
The direct interpolation into the HTML field is visible in the example, and no escaping or sanitization step is shown.
中
references/routing.md:100-105
Inbound Email Contents Are Written to Logs
The parsing example logs the full subject and text of incoming messages. Email bodies can contain personal data, reset links, or secrets that should not enter routine logs.
The example directly passes parsed subject and body text to console.log. The exposure is clear, although retention and access depend on deployment settings.

Add Transactional Email

Configure a Worker binding and send account notifications with plain-text and HTML content.

Build an Inbound Support Mailbox

Route incoming messages to a Worker, parse them, store them, and prepare reviewed replies.

Improve Delivery Health

Check authentication records, suppression handling, sending limits, and analytics for a production email domain.

これらのプロンプトを試す

Configure a Worker Binding 
Add Cloudflare Email Sending to my Worker. Show the Wrangler configuration and a basic transactional welcome email with text and HTML.
Send Through the REST API 
Create a Cloudflare Email Service REST request for my external application. Use environment-based credentials and explain the response states.
Process Incoming Email 
Design an Email Routing handler that parses one raw message, validates the sender, stores metadata, and forwards only to verified destinations.
Design a Reviewed AI Mailbox 
Design a secure support mailbox using Email Routing, Durable Objects, and an AI drafting agent. Include prompt-injection controls, approval, sanitization, and observability.

ベストプラクティス

  • Use Workers bindings when possible and keep REST API tokens in managed secrets.
  • Verify sending domains and include both plain-text and HTML message bodies.
  • Treat inbound messages as untrusted and review agent-generated replies before sending.

回避

  • Do not hardcode API tokens or expose them in logs and examples.
  • Do not use transactional email infrastructure for newsletters or unsolicited bulk messages.
  • Do not insert untrusted text into outgoing HTML without escaping or sanitization.

よくある質問

Can this skill send email from a Cloudflare Worker?
Yes. It explains the Email Sending binding, domain onboarding, message fields, attachments, errors, and restricted destinations.
Can it support applications outside Workers?
Yes. It documents the Cloudflare REST API and credential handling for Node.js, Python, Go, and other clients.
Does it handle incoming email?
Yes. It covers Email Routing handlers, forwarding, rejection, MIME parsing, storage, and threaded replies.
Is it suitable for marketing campaigns?
No. Cloudflare Email Service is described here for transactional email, not newsletters or bulk marketing campaigns.
Does it configure DNS authentication?
It explains onboarding and verification for SPF, DKIM, and DMARC. Actual DNS changes still require account access and user approval.
How should AI-generated replies be secured?
Treat email as untrusted data, restrict agent tools, sanitize outgoing HTML, and require human approval before sending.
