Overview

Affected versions of this package are vulnerable to Improper Input Validation. It does not perform hostname validation when connecting to the configured SMTP server. This lack of validation could be abused using a man-in-the-middle attack to intercept these connections.Mailer Plugin 1.32.1 validates the SMTP hostname when connecting via TLS by default.
