Grafana is an open-source platform for monitoring and observability. Prior to versions 8.5.16 and 9.2.8, malicious user can create a snapshot and arbitrarily choose the originalUrl parameter by editing the query, thanks to a web proxy. When another user opens the URL of the snapshot, they will be presented with the regular web interface delivered by the trusted Grafana server. The Open original dashboard button no longer points to the to the real original dashboard but to the attacker’s injected URL. This issue is fixed in versions 8.5.16 and 9.2.8.
