CVE-2023-1387
If an attacker has access to the data source, the leaked token could be used to authenticate to Grafana.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.50%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
