How Message-Level Raw Option Bypass happens in Node.js Nodemailer and how to fix it

A high-severity vulnerability in Nodemailer (GHSA-p6gq-j5cr-w38f) allowed attackers to bypass the `disableFileAccess` and `disableUrlAccess` security controls by using the message-level `raw` option, enabling arbitrary file reads and full-response SSRF in delivered emails. The fix upgrades Nodemailer from version 6.10.1 to 9.0.1, closing this bypass at the library level. This is especially critical for applications that allow any user-influenced content to flow into email composition.

How Message-Level Raw Option Bypass happens in Node.js Nodemailer and how to fix it

A high-severity vulnerability in Nodemailer (versions before 9.0.0) allowed the `raw` message option to completely bypass `disableFileAccess` and `disableUrlAccess` security controls, enabling attackers to read arbitrary files from the server filesystem and perform full-response Server-Side Request Forgery (SSRF) in delivered email messages. Upgrading from `^8.0.10` to `^9.0.4` in `backend/package-lock.json` closes this exploit primitive by enforcing access restrictions consistently across all m

How Nodemailer raw option bypass happens in Node.js and how to fix it

A high-severity vulnerability in Nodemailer versions prior to 9.0.1 allowed attackers to bypass the `disableFileAccess` and `disableUrlAccess` security controls using the message-level `raw` option. This bypass enabled arbitrary file reads from the server and full-response Server-Side Request Forgery (SSRF) attacks, potentially exposing sensitive configuration files and internal network resources. The fix involves upgrading Nodemailer from version 8.0.7 to 9.0.1.

CVE-2025-14874: Nodemailer DoS via Crafted Email Address Header

CVE-2025-14874 is a high-severity Denial of Service vulnerability in Nodemailer that allows an attacker to crash an application by sending a specially crafted email address header. The vulnerability existed in Nodemailer versions prior to 7.0.11 and was present in the `Dise-ador-experto-master` project's `package-lock.json` dependency on version 6.10.1. Upgrading to Nodemailer 7.0.11 resolves the issue by fixing the underlying header parsing logic that could be exploited to cause unbounded resou
