CVE-2022-31130: 
Grafana vulnerability analysis and mitigation

CVE-2022-31130 is a security vulnerability discovered in Grafana, an open source observability and data visualization platform. The vulnerability was identified on June 26, 2022, when a security researcher reported that the GitLab data source plugin could leak API keys. This issue affects Grafana versions prior to 9.1.8 and 8.5.14, where data source and plugin proxy endpoints could leak authentication tokens under certain conditions (GitHub Advisory).

The vulnerability has been assigned a CVSS score of 4.9 (MODERATE) with the vector string CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N. The issue specifically affects data source and plugin proxy endpoints with authentication tokens, where the destination plugin could receive a user's Grafana authentication token (GitHub Advisory, CVE).

The primary impact of this vulnerability is that destination plugins could receive Grafana authentication tokens belonging to users, potentially leading to unauthorized access to user data and functionality. This represents a significant confidentiality breach in the authentication mechanism (GitHub Advisory).

The vulnerability has been patched in Grafana versions 9.1.8 and 8.5.14. As a temporary workaround, users are advised not to use API keys, JWT authentication, or any HTTP Header based authentication. The patches have been applied to Grafana Cloud, and cloud providers licensed to offer Grafana Pro have been notified and have secured their offerings (GitHub Advisory).
