## Technical details

The Visualizer plugin for WordPress (versions up to 4.0.3) contains an authorization bypass vulnerability due to missing capability checks on a custom-registered REST API route. While the standard WordPress REST endpoint for the 'visualizer' custom post type correctly enforces permissions, the plugin-specific route `/wp-json/visualizer/v1/action/{chart}/{type}/` does not. This allows unauthenticated remote attackers to bypass intended access controls and export chart data (including draft, private, pending, future, or trashed posts) as CSV, Excel, or HTML. The vulnerability is classified as CWE-862 (Missing Authorization).
