# Security Policy Nodemailer is a widely deployed, zero-dependency e-mail library. We take security reports seriously and aim to respond quickly. ## Supported Versions Security fixes are released only against the latest major version. We do not backport patches to older majors — upgrading to the current release line is the supported way to receive security updates. | Version | Supported | | ------- | ------------------ | | 8.x | :white_check_mark: | | < 8.0 | :x: | If you are on an older major, please upgrade. See the migration notes at before updating. ## Reporting a Vulnerability **Please do not report security vulnerabilities through public GitHub issues, pull requests, or discussions.** Report privately through one of the following channels: 1. **GitHub Security Advisories (preferred).** Open a private report at . This keeps the discussion private until a fix is published and lets us credit you. 2. **Email.** Send details to **andris@reinman.eu** (the contact listed in [`SECURITY.txt`](SECURITY.txt)). Encrypt sensitive details if possible. When reporting, please include as much of the following as you can: - The affected version(s) and environment (Node.js version, OS). - The component involved (e.g. SMTP connection, address parsing, MIME/header generation, DKIM). - A clear description of the issue and its impact (e.g. header/SMTP command injection, information disclosure, DoS). - A minimal proof of concept or reproduction steps. - Any suggested remediation, if you have one. Nodemailer is maintained by a single person, so there is no guaranteed response time — sometimes reports are handled within hours, sometimes they take longer. Accepted issues are fixed in a new release and coordinated through a GitHub Security Advisory, and reporters who wish to be named are credited. ## CVEs We track and disclose vulnerabilities through GitHub Security Advisories. We do not request or manage CVE identifiers ourselves. If you need a CVE assigned for a reported issue, please request one yourself — for example, through GitHub's own CVE request flow on the published advisory, or another CNA. ## Scope In scope: the `nodemailer` package source in this repository — message and MIME generation, SMTP/LMTP client behaviour, address parsing, header handling, DKIM signing, and the bundled transports. Out of scope: vulnerabilities in your own application code, misconfiguration of your mail server or credentials, social-engineering reports, and issues in third-party services Nodemailer connects to. Thank you for helping keep Nodemailer and its users safe.
