Impact
The malicious user is able to discover services in the internal network through webhook functionality. All installations accepting public traffic are affected.
Patches
Webhook payload URLs are revalidated before each delivery to make sure they are not resolved to blocked local network addresses. Users should upgrade to 0.12.8 or the latest 0.13.0+dev.
Workarounds
Run Gogs in its own private network.
