I haven't found a clear answer to this:

CloudFlare has multiple SSL configurations:

> Flexible SSL: There is an encrypted connection between your website visitors and Cloudflare, but not from Cloudflare to your server.

> Full SSL: Encrypts the connection between your website visitors and Cloudflare, and from Cloudflare to your server

(I'll add Full SSL mode still involves CloudFlare terminating SSL (decrypting) before re-encrypting to communicate to your server)

If I am running in Full SSL mode, is (or was) my data vulnerable to being leaked?

Full SSL requests still terminate at CloudFlare, and would still be vulnerable. It's just that CloudFlare's connection to your origin is also encrypted.

  • Thanks. Wish they had explicitly stated that all SSL modes were affected (unless I missed it...)
