Doc Text:	A Cross-site scripting (XSS) vulnerability was found in the way Grafana handles data sources. This flaw allows an attacker to serve HTML content through the Grafana data source or plugin proxy and trick a user to visit this HTML page using a specially crafted link and execute a Cross-site scripting (XSS) attack. Should an existing data source connected to Grafana be compromised, it could be used to inappropriately gain access to other data sources connected to the same Grafana org.	Story Points:	---
