Overview<\/strong><\/p>\n

In this blog post, we are going to discuss a potentially serious security vulnerability identified as CVE-2025-3260. This vulnerability is found in the \/apis\/dashboard.grafana.app\/* endpoints and affects all API versions. The exploit allows authenticated users to bypass<\/a> dashboard and folder permissions, enabling them to view, edit, or delete dashboards\/folders without the necessary permissions. This vulnerability does not only impact the system’s integrity but also poses a threat<\/a> to data confidentiality. Therefore, understanding the nature of this vulnerability, its potential impact, and possible mitigation steps is crucial<\/a> for all organizations utilizing Grafana’s APIs.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-3260
\nSeverity: High (8.3 CVSS score)
\nAttack Vector: Network
\nPrivileges Required: Low
\nUser Interaction: None
\nImpact: Potential system compromise or data leakage<\/a> due to bypassing of dashboard and folder permissions<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Grafana API Endpoints<\/a> | v0alpha1, v1alpha1, v2alpha1<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit works by manipulating the API requests sent to the \/apis\/dashboard.grafana.app\/* endpoints. Authenticated users, including viewers, editors, and anonymous users with viewer\/editor roles, can utilize the exploit to bypass dashboard and folder permissions<\/a>. This allows them to view, edit, delete, and create dashboards\/folders without having the required permissions. However, it’s worth noting that the vulnerability does not affect<\/a> organization isolation boundaries and does not grant access to datasources.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here is a conceptual example of how the vulnerability might be exploited in an HTTP request<\/a>:<\/p>\n

GET \/apis\/dashboard.grafana.app\/v1alpha1\/dashboards HTTP\/1.1\nHost: target.example.com\nAuthorization: Bearer \n{ }<\/code><\/pre>\n
In this example, an attacker who has obtained an authentication token can send a GET request to view all the dashboards, bypassing the restrictions<\/a> set in place. It’s important to note that this is a simplified example, and real-world exploitation may involve more complex methods and payload configurations.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
To mitigate this vulnerability, vendors have released patches that should be applied promptly. If you cannot apply the patch immediately, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can provide temporary mitigation. However, these measures are not a permanent solution and can only serve as a stopgap until you can apply the vendor\u2019s patch. It’s also recommended to regularly review and tighten your dashboard and folder permissions to minimize the risk of unauthorized<\/a> access.<\/p>\n","protected":false},"excerpt":{"rendered":"
