CVE-2022-21673: OAuth Identity Token exposure in Grafana
First published: Tue Jan 18 2022(Updated: )
An information-disclosure flaw was found in grafana. When a data source has the Forward OAuth Identity feature enabled, sending a query to that data source with an API token (and no other user credentials) will forward the OAuth Identity of the most recently logged-in user. This flaw allows API token holders to retrieve data to which they may not be authorized.
