{"id":"UBUNTU-CVE-2023-1387","details":"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.","modified":"2025-10-24T05:01:09Z","published":"2023-04-26T14:15:00Z","upstream":["CVE-2023-1387"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-1387"},{"type":"REPORT","url":"https://grafana.com/security/security-advisories/cve-2023-1387/"},{"type":"REPORT","url":"https://github.com/grafana/bugbounty/security/advisories/GHSA-5585-m9r5-p86j"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-1387"}],"affected":[{"package":{"name":"grafana","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/grafana@2.6.0+dfsg-1?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.6.0+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_name":"grafana","binary_version":"2.6.0+dfsg-1"},{"binary_name":"grafana-data","binary_version":"2.6.0+dfsg-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-1387.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:H/UI:R/S:U/C:H/I:N/A:N"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"type":"Ubuntu","score":"low"}]}
