Doc Text:
A flaw was found in Grafana. This flaw allows a remote, authenticated attacker to obtain sensitive information caused by an issue when enabling the "url_login" configuration option. By sending a specially crafted request, an attacker can obtain JWT information and use this to launch further attacks against the affected system.

Where an attacker has control on a datasource, the JWT token can be leaked to the data source when the GF_AUTH_JWT_URL_TOKEN is set to true.
