Gabriel 36dece43c7 Fix: Upgrade Nodemailer to address SMTP command injection vulnerability (#19151)
📄 Summary

This PR upgrades the nodemailer dependency to a secure version (≥ 8.0.4)
to fix a known SMTP command injection vulnerability
(GHSA-c7w3-x93f-qmm8).

🚨 Issue

The current version used in twenty-server (^7.0.11, resolved to 7.0.11 /
7.0.13) is vulnerable to SMTP command injection due to improper
sanitization of the envelope.size parameter.
This could allow CRLF injection, potentially enabling attackers to add
unauthorized recipients to outgoing emails.

🔍 Root Cause

The vulnerability originates from insufficient validation of
user-controlled input in the SMTP envelope, specifically the size field,
which can be exploited via crafted input containing CRLF sequences.

 Changes
Upgraded nodemailer to version ^8.0.4
Ensured compatibility with existing email sending logic
Verified that no breaking changes affect current usage

🔐 Security Impact

This update mitigates the risk of:

SMTP command injection
Unauthorized email recipient manipulation
Potential data leakage via crafted email payloads

Why Twenty

We built Twenty for three reasons:

CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.

A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.

We believe in open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
