Security vulnerabilities and automated fixes for file read issues

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.
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.
