Overview

AI description

Automated description summarized from trusted sources.

CVE-2025-4123 is a cross-site scripting (XSS) vulnerability found in Grafana. It stems from a combination of client path traversal and an open redirect issue within the handling of custom frontend plugins. This flaw allows attackers to redirect users to malicious websites and execute arbitrary JavaScript code. The vulnerability is particularly concerning because it can be exploited even without editor permissions, especially if anonymous access is enabled in Grafana. Furthermore, if the Grafana Image Renderer plugin is installed, the vulnerability can be escalated to a full read Server-Side Request Forgery (SSRF), potentially exposing internal services and cloud metadata. All supported versions of Grafana OSS and Grafana Enterprise, starting from Grafana 8 are affected.

Description: 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.
