CVE-2015-5739: XSS
First published: Wed Aug 05 2015(Updated: )
Go is vulnerable to HTTP request smuggling, caused by a flaw in net/http library in net/textproto/reader.go. By sending a specially-crafted HTTP request with a space instead of a hyphen, an attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks.
