HighSummary
In nodemailer v9.0.0, the message-level `raw` option bypasses `disableFileAccess` and `disableUrlAccess` protections, enabling arbitrary file reads and full SSRF (Server-Side Request Forgery) in the sent message.
Risk Assessment
An attacker can read sensitive files from the server (e.g., configuration files, keys) or make requests to internal network resources, leading to data leakage and attack escalation.
Recommendation
Immediately update the nodemailer library to a version newer than 9.0.0 that includes a fix for this security bypass.
Other vulnerabilities in nodemailer
See all- GHSA-r7g4-qg5f-qqm2Medium
Nodemailer disables TLS certificate verification in its internal HTTPS fetch client by setting rejectUnauthorized: false in lib/fetch/index.js. This causes OAuth2 token requests to trust invalid or self-signed HTTPS certificates.
- GHSA-268h-hp4c-crq3Medium
A vulnerability in the Nodemailer library allows header injection via the `list.*.comment` field, which is not sanitized for CR (`\r`) and LF (`\n`) characters. An attacker can supply a malicious value in this field, leading to email header spoofing.
- GHSA-wqvq-jvpq-h66fMedium
A vulnerability in Nodemailer allows bypassing the `disableFileAccess` and `disableUrlAccess` options when using `jsonTransport`. While the normal MIME streaming path enforces these restrictions, `jsonTransport` serializes the message in a way that bypasses them, potentially enabling access to local files or external URLs.
