Overview
org.webjars.npm:nodemailer is an Easy as cake e-mail sending from your Node.js applications
Affected versions of this package are vulnerable to Interpretation Conflict through _normalizeAddress in lib/mime-node/index.js. An attacker can cause mail to be delivered to an attacker-controlled domain by supplying a recipient address whose domain contains an IDN-mapped or ignored code point, such as an invisible soft hyphen, that a standards-compliant domain check resolves to a trusted domain but Nodemailer encodes to a different xn-- label. This can make an application approve or display one recipient domain while Nodemailer sends the message to another external domain, exposing the intended email content and breaking domain-based recipient controls.
