CVE-2023-3010Network attack vector

Authenticated script execution via unvalidated legend color

Published Oct 25, 2023 · Updated Jun 12, 2025

DOM XSS in Grafana Labs Worldmap Panel 0.3.30 through 1.0.3 allows remote authenticated users to execute script in viewers' browsers. The legend renderer accepts an unchecked color value from panel configuration and inserts it into DOM content rather than restricting it to valid color syntax. Low-privilege access is required to save crafted panel settings, and another user must view the affected dashboard; script runs with that viewer's Grafana origin privileges.
