CVE-2026-15026: Auth Bypass (CVSS 4.3)

Description

The Import and export users and customers plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.4.0 via the email_template_selected. This makes it possible for authenticated attackers, with subscriber-level access and above, to extract the post_title and raw post_content of arbitrary posts regardless of status (draft, private, future, trash, password-protected) or post type (including non-public CPTs such as WooCommerce orders and internal CRM records) by enumerating post IDs. The required codection-security nonce is exposed as inline JavaScript on any wp-admin page when ?post_type=acui_email_template is appended to the URL, which is reachable by any authenticated user including Subscribers.
