Grafana is an open-source platform for monitoring and observability.
Starting with the 9.1 branch, Grafana introduced the ability to search for
a JWT in the URL query parameter auth_token and use it as the
authentication token. By enabling the “url_login” configuration option
(disabled by default), a JWT might be sent to data sources. If an attacker
has access to the data source, the leaked token could be used to
authenticate to Grafana.
