This is due to the fact that the /render/csv endpoint lacked validation of the filePath parameter that allowed an attacker to save a shared object to an arbitrary location that is then loaded by the Chromium process.

Instances are vulnerable if:

1. The default token (\"authToken\") is not changed, or is known to the attacker.
2. The attacker can reach the image renderer endpoint.

This issue affects grafana-image-renderer: from 1.0.0 through 4.0.16.
