Verify SPF, DKIM, and DMARC alignment.
Review bounces, suppressions, and delivery analytics.
Use accurate subjects, complete text content, and valid unsubscribe handling where required.

安全审计

中风险

v1 • 2026/8/9 打开版本化报告

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:111 references/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.

你能构建什么

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.

试试这些提示

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.

最佳实践

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.

避免

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.
