CVE-2026-72766 · n8n before 1.123.67 Arbitrary File Read via Send Email Node
This page contains facts from public vulnerability sources. Check the original advisory before updating.
n8n before 1.123.67, 2.x before 2.31.5, and 2.32.x before 2.32.1 contain a type confusion vulnerability in the Send Email node, which does not enforce that its message fields are strings. A crafted non-string value supplied from a workflow expression into the text or HTML body field can be interpreted by the underlying mail library (Nodemailer) as a file path or URL, allowing arbitrary local file disclosure and server-side request forgery (SSRF). Exploitation requires a pre-existing active workflow with an unauthenticated webhook, valid SMTP credentials configured on the node, and untrusted input mapped directly into the body field; this is not a default configuration.
