What is CVE-2026-13468?
CVE-2026-13468 is a high-severity missing authorization vulnerability in themeisle Visualizer – Tables & Charts Manager with Built-in AI Generator, published on 1 Jul 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official 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.
Weakness: CWE-862
