Vulnerability disclosure on SSL for SaaS v1 (Managed CNAME)

8/1/2025

This post details a vulnerability in the older SSL for SaaS v1 (Managed CNAME) product, where IP-based routing and lack of domain ownership verification allowed for potential Man-in-the-Middle attacks. It explains the architectural difference between v1 and the newer Cloudflare for SaaS v2, highlighting how v2's verified custom hostname model with hostname verification and pre-validation closes this security gap. Compensating controls like an allowlist and WAF custom rules are implemented for remaining v1 users, and the post emphasizes the ongoing migration to the secure, validated v2 model.

The easiest way to build a modern SaaS application

9/21/2022

This post announces the General Availability (GA) of Workers for Platforms for Cloudflare Enterprise customers.

It also highlights the removal of the script limit for these customers and introduces Dynamic Dispatch Namespaces, a mechanism for Dispatch Workers to call User Workers without explicit pre-definition, addressing limitations of Service Bindings in this context. The post provides code examples for Dispatch Worker configuration and User Worker upload, along with a link to an example application and developer documentation.

Security for SaaS providers

Introduced WAF for SaaS, enabling SaaS providers to create and deploy distinct WAF rule sets for their customers. This is facilitated by associating custom metadata (e.g., 'security_level') with custom hostnames, which can then be leveraged within the Ruleset Engine to trigger specific security product configurations like WAF, Firewall Rules, and Advanced Rate Limiting. Also announced a free tier for Cloudflare for SaaS (100 custom hostnames) and reduced custom hostname pricing to $0.10/month.

Incorrect proxying of 24 hostnames on January 24, 2022

1/26/2022

This post details an incident where a product migration for Cloudflare for SaaS resulted in 24 hostnames being incorrectly proxied to the clickfunnels.com origin. The root cause was identified as a bug in the migration process that erroneously moved 'blocked' hostnames to an 'active' state. Procedural and technical follow-ups were implemented, including: no more blocked hostname overrides, explicit customer validation for blocked hostnames during migration, additional monitoring for migrated hostnames and www.cloudflare.com, and staging hostname activations on non-production elements before production promotion.
