How Denial of Service via Crafted Email Headers Happens in Node.js and How to Fix It

A high-severity denial-of-service vulnerability (CVE-2025-14874) in Nodemailer versions prior to 7.0.0 allowed attackers to crash Node.js email-sending services by supplying specially crafted email address headers. The fix upgrades the `nodemailer` dependency in `clay-server` from version 6.10.1 to 9.0.5, closing the attack surface against malformed input. Any application that passes user-influenced data into Nodemailer's address parsing logic is affected and should upgrade immediately.

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

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
