    • Gitlab uses an UrlBlocker class to prevent malicious users from exploiting SSRF via the webhook URL. This class validates the URL and blocks everything which is a local network, but before the 11.5.1 version, they didn't think about an IPv6 format, which maps to IPv4: [0:0:0:0:0:ffff:127.0.0.1]. Replacing the part of 127.0.0.1 to any IP address also worked, and this vulnerability made it possible to send requests to the internal network of a GitLab instance.
