An issue was discovered in GitLab Community and Enterprise Edition 10.1 through 12.2.1. Protections against SSRF attacks on the Kubernetes integration are insufficient, which could have allowed an attacker to request any local network resource accessible from the GitLab server.
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
