Similar to the HeartBleed Bug, but different. May affect security and account information on many websites. Password changes are advisable.

This is regarding a recent vulnerability exposed in Cloudflare's infrastructure. For months now, there has been a vulernerability that allowed data transmitted between Cloudflare's proxy servers and the target server to be exposed.

Affected sites can be found in this list:
https://github.com/pirate/sites-using-cloudflare


Sources:
https://bugs.chromium.org...ject-...detail?id=1139

https://www.reddit.com/r/...in/co...flare_reverse/

Cloudflare is now finding a solution for this, for now just keep safe.

    I am not sure what you mean. "Problems"? Such as what? This thread isn't about website issues. This thread relates to the massive dump of random user information from hundreds or thousands of websites such as user's locations, passwords, user names, private messages, credit card information, and of course potentially their public non-sensitive information as well. There are examples of actual information which was dumped, in the links above. The CloudFlare service started to overrun its buffers in certain situations and puke out additional information to anyone who happened to view it (including search engines). Any sensitive information you have saved, stored, or recorded on any website which uses CloudFlare (many) could potentially now be out there in someone's hands. I don't think that there is any way to know or measure the potential impact at this time.

    If you need to check your exposure, hit bleed.cloud to quickly domains or scan your exposure.

    Cloudflare has already messaged the domains of which may have issues. There is no need to specifically look into a domain if you aren't the owner of said domain and using Cloudflare as a caching provider. There happens to be a list (growing) of which can be checked against but, for the most part, quite a number of domains did not have issue with compromise. Changing your passwords on any listed site is a very good idea. [Listing of sites possibly affected]
