Associated Vulnerability

Title: WordPress Visualizer插件跨站脚本漏洞 (CVE-2019-16931)
Description:A stored XSS vulnerability in the Visualizer plugin 3.3.0 for WordPress allows an unauthenticated attacker to execute arbitrary JavaScript when an admin or other privileged user edits the chart via the admin dashboard. This occurs because classes/Visualizer/Gutenberg/Block.php registers wp-json/visualizer/v1/update-chart with no access control, and classes/Visualizer/Render/Page/Data.php lacks output sanitization.

Description

WordPress Visualizer plugin before 3.3.1 contains a stored cross-site scripting vulnerability via /wp-json/visualizer/v1/update-chart WP-JSON API endpoint. An unauthenticated attacker can execute arbitrary JavaScript when an admin or other privileged user edits the chart via the admin dashboard.
