CVE-2022-2370Public exploitNetwork attack vector

Subscriber-level SMTP credential disclosure via unchecked settings data

Published Aug 1, 2022 · Updated Aug 3, 2024

Missing authorization in YayCommerce YaySMTP before 2.2.1 allows remote authenticated users to read configured SMTP credentials. The settings-page bootstrap emits the full mailer configuration in the yaySmtpWpData JavaScript object without first checking a WordPress capability. Subscriber-level wp-admin access and a configured non-default mailer are sufficient, exposing reusable mail-service secrets without changing site data.
