CVE-2022-31176 – Grafana Image Renderer leaking files

https://notcve.org/view.php?id=CVE-2022-31176

Grafana Image Renderer is a Grafana backend plugin that handles rendering of panels & dashboards to PNGs using a headless browser (Chromium/Chrome). An internal security review identified an unauthorized file disclosure vulnerability. It is possible for a malicious user to retrieve unauthorized files under some network conditions or via a fake datasource (if user has admin permissions in Grafana). All Grafana installations should be upgraded to version 3.6.1 as soon as possible. As a workaround it is possible to [disable HTTP remote rendering](https://grafana.com/docs/grafana/latest/setup-grafana/configure-grafana/#plugingrafana-image-renderer). • https://github.com/grafana/grafana-image-renderer/pull/364 https://github.com/grafana/grafana-image-renderer/security/advisories/GHSA-2cfh-233g-m4c5 https://security.netapp.com/advisory/ntap-20221209-0004 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-306: Missing Authentication for Critical Function •
