Technical details
The vulnerability is a server-side request forgery (SSRF) in Grafana's Git Sync feature. An Organization Admin can misconfigure the server or token URL of a Git Sync connection to point to loopback (127.0.0.1) or internal network addresses. Grafana will then send sensitive credentials—including OAuth client secrets, tokens, and GitHub App private keys—to the attacker-controlled endpoint. The attack requires Organization Admin role privileges.
