Description Todd Cullum 2022-01-24 20:43:43 UTC

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.
