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.
Automated scanner template
A ready-made Nuclei template detects this vulnerability automatically. Vulnerabilities with public scanner templates are typically probed across the internet soon after the template appears — exposed systems should be patched first.
