On this page
A user with the Organization Admin role could point the server or token URL of a Git Sync connection at a loopback or internal address, and Grafana would then send the connection's OAuth client secret and tokens, or requests signed with the GitHub App private key, to that address (server-side request forgery).

Red Hat
Red Hat rates this Moderate.
This vulnerability is rated as Moderate because successful exploitation requires pre-existing organization administrator privileges to configure Git integration targets, limiting the scope of attack to privileged roles. In affected environments using Git Sync or gitOAuth connections, Grafana may transmit authentication secrets to internal or loopback addresses if improperly configured. Environments that do not utilize Git Sync features or where administrative access is tightly controlled remain protected from credential exposure.
Audit existing Git Sync and OAuth connector configurations within the Grafana administrative interface to verify that all connection URLs point exclusively to trusted, external repositories rather than loopback or internal network destinations.
Additionally, enforce egress network filtering on the host or container network to restrict outbound traffic from the Grafana process to internal subnets and local loopback addresses, allowing connections only to verified Git server hosts.
Caveat: Restricting outbound network traffic may disrupt legitimate connections to internal data sources, alert endpoints, or local authentication providers if network filtering rules are overly restrictive.
