CVE-2026-13468

Visualizer <= 4.0.3 - Missing Authorization to Unauthenticated Sensitive Information Disclosure via /visualizer/v1/action/{chart}/{type}/ REST Endpoint

Published Jul 1, 2026 CVSS 3.1 · 7.5 High EPSS < 1% KEV · Not listed
Description
The Visualizer – Tables & Charts Manager with Built-in AI Generator plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.0.3. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to access and export the contents of any visualizer chart on the site — including charts in draft, private, pending, future, or trash status — as CSV, Excel, or HTML via the /wp-json/visualizer/v1/action/{chart}/{type}/ REST endpoint. This bypass is particularly impactful because the standard WordPress REST endpoint for the non-public 'visualizer' custom post type correctly enforces capability checks and returns HTTP 401 to unauthenticated callers, whereas this plugin-registered route circumvents that protection entirely.
