Grafana version 8.4.3 has been flagged for allowing unauthenticated access via specific URIs in its interface (such as /dashboard/snapshot/*?orgId=). The issue has been assigned the Common Vulnerabilities and Exposures (CVE) identifier CVE-2022-32276. However, this vulnerability is currently disputed by the software's vendor, who considers it a user interface (UI) bug rather than a security issue.
Nonetheless, it's crucial to understand the potential risks that may arise in such scenarios and take necessary action to minimize any potential damage.
The following code snippet demonstrates an example of a vulnerable URI that could allow unauthenticated access in Grafana 8.4.3:
In this URI, <host> and <port> represent the server address and port number, respectively, where the Grafana instance is running. The wildcard * indicates that any snapshot value inserted in the path could potentially result in unauthenticated access.

- CVE Details: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-32276
As per the available information, this issue could allow unauthorized users to access restricted Grafana resources by merely sending strategically constructed HTTP requests via specific URIs. Since Grafana is a popular platform for monitoring and observability, unauthorized access could potentially lead to sensitive data exposure, the alteration of critical data, or unauthorized access to connected data sources.
Grafana has officially disputed the classification of this issue as a vulnerability, considering it a UI bug instead. The vendor has addressed this bug in version 8.4.4 and later, and the risk profile may not warrant the same level of concern it would otherwise receive as a confirmed vulnerability.
Users of Grafana should thoroughly assess their installations to determine the validity and impact of this discovery, stay informed of updates from the vendor, and apply the latest updates or patches as deemed necessary.
While the classification of CVE-2022-32276 as a vulnerability is disputed by Grafana, it's essential to stay informed about potential risks in any software implementation. Administrators should carefully consider their instance's exposure, follow Grafana's official statements on this issue, and adopt any recommendations or newer versions released to address it.
