I'm a Cloudflare (free) customer, and I've had no email or contact of any kind from Cloudflare.

My understanding from reading this and Travis' post is that all Cloudflare customers are affected, is that correct?

Basically yes. If some of your traffic was flowing through a server on which any customer had the vulnerable features enabled, parts of your traffic may have been dumped.

No. If you have any of those features enabled Email obfuscation, Server-side Excludes and Automatic HTTPS Rewrites as well as you have an invalid HTML markup. Per their blog post it is 0.00003% of the total requests.

I thought those were the conditions that caused PII to be included in the HTML response, but the PII could come from any customer as it's a buffer overrun situation. Damn this is confusing
