CVE-2026-13468: Visualizer <= 4.0.3 - Missing Authorization to Unauthenticated Sensitive Information Disclosure via /visualizer/v1/action/{chart}/{type}/ REST Endpoint

• Severity: high (CVSS 7.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.6% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-07-01 · updated 2026-07-01
• Weakness: CWE-862

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.
