Cloudbleed (also known as CloudLeak and CloudFlare Bug) is a security bug discovered on February 17, 2017 affecting Cloudflare's reverse proxies, which caused their edge servers to run past the end of a buffer and return memory that contained private information such as HTTP cookies, authentication tokens, HTTP POST bodies, and other sensitive data. Some of this data was cached by search engines.
