Overview

org.apache.commons:commons-email aims to provide a API for sending email.

Affected versions of the package are vulnerable to SMTP Header Injection. When a call-site passes a subject for an email that contains line-breaks in Apache Commons Email 1.0 through 1.4, the caller can add arbitrary SMTP headers.
