## Overview

Grafana OSS and Grafana Enterprise did not safely resolve symbolic links when
extracting plugin archives. A crafted plugin archive can chain relative symbolic link
entries to escape the plugin installation directory, writing arbitrary files and an
executable backend binary outside that directory. The dropped executable runs with the
privileges of the Grafana server process, resulting in remote code execution.

Plugin archives are extracted before their signature is verified, so a valid plugin
signature does not prevent the write. An operator can therefore be affected by
installing a plugin that appears legitimate, as well as by installing a plugin from an
arbitrary archive using grafana-cli, the GF_INSTALL_PLUGINS environment variable, or
preinstall configuration.

Grafana Enterprise is affected because it includes the same plugin extraction code as
Grafana OSS.
