CVE-2024-6694Network attack vector

SMTP credential disclosure via populated settings field

Published Jul 20, 2024 · Updated Apr 8, 2026

Information exposure in WP Mail SMTP 4.0.1 and earlier allows remote authenticated users to read the configured SMTP password. The settings renderer in src/Providers/OptionsAbstract.php places the stored SMTP password into the password input value when the settings page opens. WordPress administrator-level access is required, and the consequence is limited to disclosure of the supplied server's SMTP credential.
