Privilege Escalation Vulnerability in Volkov Labs Business Links for Grafana

CVE-2025-58746

What is CVE-2025-58746?

CVE-2025-58746 is a privilege escalation vulnerability found in the Volkov Labs Business Links plugin for Grafana, which is widely used for data visualization and monitoring in various IT environments. This plugin enables users to create and manage a visual interface for navigating internal dashboards, external links, and other navigational elements. The vulnerability is present in versions prior to 2.4.0 and stems from a flaw that allows users with Editor privileges to elevate their access to Administrator levels. This unauthorized privilege escalation is made possible due to the plugin's acceptance of arbitrary JavaScript code within a specific configuration field, posing a substantial risk to organizations that utilize this plugin. If exploited, a malicious actor could perform a range of administrative functions, potentially compromising the integrity and security of the entire Grafana instance and the data it manages.

Potential impact of CVE-2025-58746

1. Unauthorized Access and Control: The most significant impact of this vulnerability is the ability for individuals with lower-level access (Editor privileges) to gain elevated access to Administrator functions. This could enable them to modify sensitive configurations, access confidential data, and manage user roles, thereby leading to unauthorized information exposure.

2. Operational Disruption: Attackers exploiting this vulnerability could disrupt organizational operations by altering or deleting critical dashboards, corrupting data, and rendering Grafana instances inoperable. Such actions could hinder an organization's ability to make timely data-driven decisions based on visual insights.

3. Data Integrity and Security Risks: With escalated privileges, an attacker could manipulate or exfiltrate underlying data, leading to significant risks concerning data integrity and security. This could result in data breaches, potential loss of intellectual property, and erosion of customer trust, impacting the organization's reputation and compliance with data protection regulations.
