{"id":"UBUNTU-CVE-2026-11817","details":"This vulnerability only affects Grafana stacks configured with multiple organizations; single-organization deployments are not impacted. In a multi-organization stack, a user who is an Org Admin of a single organization can call GET /api/access-control/users/permissions/search?actionPrefix=dashboards: and receive permission data belonging to other organizations. The disclosed data is limited to dashboard and folder identifiers (UIDs) and per-user permission/scope mappings (which user holds which access on which dashboard). Dashboard contents, panels, query results, datasource credentials, secrets, and personal data are not exposed. This is a limited cross-organization information disclosure affecting multi-org deployments only.","modified":"2026-08-19T13:31:29.007938316Z","published":"2026-08-17T22:16:00Z","upstream":["CVE-2026-11817"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-11817"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-11817"},{"type":"REPORT","url":"https://grafana.com/security/security-advisories/cve-2026-11817"}],"affected":[{"package":{"name":"grafana","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/grafana?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.6.0+dfsg-1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.6.0+dfsg-1","binary_name":"grafana"},{"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/2026/UBUNTU-CVE-2026-11817.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N"},{"type":"Ubuntu","score":"medium"}]}
