Grafana Labs reports:

The vulnerability impacts Grafana Cloud and Grafana Enterprise instances, and it is exploitable if a user who should not be able to access all data sources is granted permissions to create a data source.

By default, only organization Administrators are allowed to create a data source and have full access to all data sources. All other users need to be explicitly granted permission to create a data source, which then means they could exploit this vulnerability.

When a user creates a data source via the API, they can specify data source UID. If the UID is set to an asterisk (*), the user gains permissions to query, update, and delete all data sources in the organization. The exploit, however, does not stretch across organizations — to exploit the vulnerability in several organizations, a user would need permissions to create data sources in each organization.

The vulnerability comes from a lack of UID validation. When evaluating permissions, we interpret an asterisk (*) as a wild card for all resources. Therefore, we should treat it as a reserved value, and not allow the creation of a resource with the UID set to an asterisk.

The CVSS score for this vulnerability is 6 Medium.

security@grafana.com reports:

A cross-site scripting (XSS) vulnerability exists in Grafana caused by combining a client path traversal and open redirect. This allows attackers to redirect users to a website that hosts a frontend plugin that will execute arbitrary JavaScript. This vulnerability does not require editor permissions and if anonymous access is enabled, the XSS will work. If the Grafana Image Renderer plugin is installed, it is possible to exploit the open redirect to achieve a full read SSRF. The default Content-Security-Policy (CSP) in Grafana will block the XSS though the `connect-src` directive.
