CVE-2026-72766: N8n: güvenlik açığı

Açıklama (NVD)

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.
