CVE-2022-21673

Grafana is an open-source platform for monitoring and observability. In
affected versions when a data source has the Forward OAuth Identity feature
enabled, sending a query to that datasource with an API token (and no other
user credentials) will forward the OAuth Identity of the most recently
logged-in user. This can allow API token holders to retrieve data for which
they may not have intended access. This attack relies on the Grafana
instance having data sources that support the Forward OAuth Identity
feature, the Grafana instance having a data source with the Forward OAuth
Identity feature toggled on, the Grafana instance having OAuth enabled, and
the Grafana instance having usable API keys. This issue has been patched in
versions 7.5.13 and 8.3.4.
