CVE-2018-7187: OS Command Injection
First published: Fri Feb 16 2018(Updated: )
The "go get" implementation in Go 1.9.4, when the -insecure command-line option is used, does not validate the import path (get/vcs.go only checks for "://" anywhere in the string), which allows remote attackers to execute arbitrary OS commands via a crafted web site.
