Detailsinfo

A vulnerability has been found in Grafana (unknown version) and classified as problematic. This vulnerability affects an unknown code block of the component Custom Frontend Plugin. The manipulation with an unknown input leads to a cross site scripting vulnerability. The CWE definition for the vulnerability is CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. As an impact it is known to affect integrity. CVE summarizes:

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.
