CVE-2026-15026

What is known

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.

Business impact

Successful exploitation of CVE-2026-15026, a medium vulnerability (CVSS 4.3) affecting the affected product, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether the affected product is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
