Grafana is vulnerable to Stored XSS. The vulnerability is due to not sanitizing the SVG image output displayed on the browser leading to arbitrary JavaScript to be executed in the context of the currently authorized user. The attacker with an editor role can achieve vertical privilege escalation by uploading a SVG file (using external URL or using data: scheme as an inline SVG) containing malicious JavaScript which can be executed by a user with Admin role while viewing a dashboard. This can allow attacker with an editor role to change to a known admin password.
