Nodemailer: Message-level raw option bypasses disableFileAccess/disableUrlAccess, enabling arbitrary file read and full-response SSRF in the delivered message
GitHub lists this reviewed advisory for nodemailer. Published version ranges and source prerequisites are shown below; this is not an inspection of a visitor’s application.
This report has not inspected your inventory, configuration, deployed build, reachability or evidence. A catalog listing and a severity score do not establish exposure or compromise.

# Message-level `raw` option bypasses `disableFileAccess` / `disableUrlAccess`, enabling arbitrary file read and full-response SSRF in the sent message - **Target:** nodemailer/nodemailer, npm `nodemailer` **v9.0.0** (HEAD `4e58450eb490e5097a74b2b2cce35a8d9e21856e`) - **Verdict:** CONFIRMED (local PoC, no network) ## Summary Nodemailer exposes `disableFileAccess` and `disableUrlAccess` so an application that passes **untrusted** message data to the library can forbid that data from reading local files or fetching URLs. Every attachment, alternative, `html`/`text`/`watchHtml`/`amp` and `icalEvent` content node honors these flags. **The message-level `raw` option does not.** `MailComposer.compile()` builds the root MIME node for a `raw` message **without** threading the two flags, so a `raw: { path: '/etc/passwd' }` or `raw: { href: 'http://169.254.169.254/…' }` message is read / fetched anyway, and the file or HTTP-response bytes become the **actual message that is sent** by every transport (SMTP, SES, sendmail, stream, JSON). An actor whose input the application intended to sandbox therefore obtains arbitrary local-file disclosure and a full-response SSRF primitive, delivered t
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
04 / Limits
What this report cannot establish
- Customer inventory, deployment, reachability and exploitation have not been inspected.
05 / Provenance
Sources you can inspect
Each assertion retains its source. Mirrored records may repeat one underlying publisher; additional links are not independent corroboration.
