Grafana Image Renderer is a Grafana backend plugin that handles rendering of panels & dashboards to PNGs using a headles

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.
