Exposure of Sensitive Information to an Unauthorized Actor

CVE-2023-1387

High
7.5/10

Summary

Grafana is an open-source platform for monitoring and observability. 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. This issue affects the versions v9.0.0-66351pre, v9.1.0-beta1 through 9.2.15, v9.3.0-beta1 through 9.3.11, v9.4.0-beta1 through 9.4.7.
