To prevent this type of exploitation from happening, starting with GitLab 10.6, all Webhook requests to the current GitLab instance server address and/or in a private network will be forbidden by default. That means that all requests made to 127.0.0.1, ::1 and 0.0.0.0, as well as IPv4 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16 and IPv6 site-local (ffc0::/10) addresses won't be allowed. |
