How to fix?

Upgrade directmailteam/direct-mail to version 5.2.4 or higher.

Overview

directmailteam/direct-mail is an advanced Direct Mail/Newsletter mailer system with sophisticated options for personalization of emails including response statistics.

Affected versions of this package are vulnerable to Information Exposure. The extension fails to check if an authenticated backend user has access to pages with newsletter subscriber data when using the "Special query" feature. Exploiting this issue leads to information disclosure, since it is possible to use the CSV export function of the extension to export subscriber data from pages the backend user does not have access to.
