Short explanation

In WordPress MB Custom Post Types & Custom Taxonomies plugin versions prior to 2.12.3, the export feature lacks a capability check, allowing users with the Contributor role to read admin‑only custom post type definitions, taxonomies, and non‑public post metadata of other users.

Why does it matter?

This enables a low‑privilege user to access sensitive content and configuration data, creating a potential data leakage risk.

What should be done?

  • Upgrade the plugin to version 2.12.3 or later
  • Manually tighten capability checks
  • Disable unnecessary export functionality
  • Conduct regular security reviews

Show the technical text from the sources

The MB Custom Post Types & Custom Taxonomies WordPress plugin before 2.12.3 does not perform a capability check in its export feature, allowing users with a role as low as Contributor to read the configuration of admin-only custom post types and taxonomies, as well as the titles, dates, statuses and some stored content of other users' non-public posts and pages.
