A user able to create or update a Cluster CRD can force the controller-manager and apiserver pods to issue outbound requests to arbitrary internal or metadata endpoints.

Vulnerability from github – Published: 2022-06-03 15:35 – Updated: 2022-06-03 15:35Impact
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.

CAPEC-664: Server Side Request Forgery
An adversary exploits improper input validation by submitting maliciously crafted input to a target application running on a server, with the goal of forcing the server to make a request either to itself, to web services running in the server’s internal network, or to external third parties. If successful, the adversary’s request will be made with the server’s privilege level, bypassing its authentication controls. This ultimately allows the adversary to access sensitive data, execute commands on the server’s network, and make external requests with the stolen identity of the server. Server Side Request Forgery attacks differ from Cross Site Request Forgery attacks in that they target the server itself, whereas CSRF attacks exploit an insecure user authentication mechanism to perform unauthorized actions on the user's behalf.
