## Technical details

A stored cross-site scripting (XSS) vulnerability exists in the Grafana TableNG panel component. The root cause is improper neutralization of input within field names, allowing an attacker with 'Editor' permissions to inject malicious JavaScript. When a victim views the affected dashboard, the script executes within the context of their browser session. This can be used to exfiltrate sensitive information or perform actions on behalf of the victim. The vulnerability is fixed in Grafana versions 12.4.4 and 13.0.2.
