Bypassing CMS Limits: Deploying a Certified security.txt via Cloudflare Workers
How to configure an RFC 9116 compliant vulnerability disclosure policy with dynamic auto-expiry, PGP signature routing, and global CORS headers.
Hey developers and SaaS builders,
Under modern security compliance frameworks—including SOC2, ISO 27001, and NIS2—hosting an active vulnerability disclosure policy has transitioned from a developer best practice to a strict corporate mandate . The global internet standard RFC 9116 defines exactly how this must be structured: via a simple text file hosted at /.well-known/security.txt.
However, many popular blogging platforms, e-commerce stores, and static CMS providers (such as Webflow, Shopify, Wix, or Blogger) do not allow users to upload custom files to the root /.well-known/ directory.
To solve this platform bottleneck, we have designed and open-sourced cloudflare-security-txt—an enterprise-grade Cloudflare Worker template to deploy your security policy globally in under 10ms.
The 3 Core Enterprise Features We Built:
⚙️ Dynamic Auto-Expiration (Zero Maintenance): RFC 9116 requires a mandatory expiration timestamp. Because developers regularly forget to update this date annually, their security files expire, triggering critical flags on automated compliance scanners . Our worker solves this by automatically calculating and updating the expiration date to exactly 1 year in the future dynamically.
🔐 Dual Route Serving (.txt & .sig): High-end compliance audits (like SOC2) require cryptographic proof that your security file has not been modified. Our worker natively supports serving both your raw security policy (/.well-known/security.txt) and its GPG cleartext signature (/.well-known/security.txt.sig) in parallel .
🌐 Global CORS Support: By enforcing Access-Control-Allow-Origin: * headers, we allow global security crawlers, automated scanners, and browser extensions to parse your security files cleanly via AJAX/fetch requests without being blocked by browser CORS restrictions.
