We believe that this vulnerability is rated at CVSS 4.3 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N). ### Impact This vulnerability only impacts the following API endpoints: - `/teams/:teamId` - an authenticated attacker can view unintended data by querying for the specific team ID. - `/teams/:search` - an authenticated attacker can search for teams and see the total number of available teams, including for those teams that the user does not have access to. - `/teams/:teamId/members` - when editors_can_admin flag is enabled, an authenticated attacker can see unintended data by querying for the specific team ID. ### Affected versions with MEDIUM severity All Grafana >=5.0.0-beta1 versions are affected by this vulnerability. ### Solutions and mitigations All installations after Grafana v5.0.0-beta1 should be upgraded as soon as possible. Appropriate patches have been applied to [Grafana Cloud](https://grafana.com/cloud) and as always, we closely coordinated with all cloud providers licensed to offer Grafana Pro. They have received early notification under embargo and confirmed that their offerings are secure at the time of this announcement. This is applicable to Amazon Managed Grafana. ### Timeline and postmortem Here is a detailed timeline starting from when we originally learned of the issue.

Grafana is an open-source platform for monitoring and observability. Affected versions of Grafana expose multiple API endpoints which do not properly handle user authorization. `/teams/:teamId` will allow an authenticated attacker to view unintended data by querying for the specific team ID, `/teams/:search` will allow an authenticated attacker to search for teams and see the total number of available teams, including for those teams that the user does not have access to, and `/teams/:teamId/members` when editors_can_admin flag is enabled, an authenticated attacker can see unintended data by querying for the specific team ID. Users are advised to upgrade as soon as possible. There are no known workarounds for this issue.
