CVE-2026-82659: nodemailer before 9.0.1 File Read and SSRF via raw option

• Severity: high (CVSS 7.1 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-08-31 · updated 2026-09-10
• Weakness: CWE-73

Description

nodemailer before 9.0.1 fails to apply disableFileAccess and disableUrlAccess flags to message-level raw option, allowing authenticated attackers to read arbitrary files or perform server-side request forgery by supplying path or href properties. Attackers can exploit this by crafting raw messages with file paths or URLs that bypass the intended sandbox, with fetched content delivered in the outgoing message to attacker-controlled recipients.

Affected products

• nodemailer: before 9.0.1 — fixed in 9.0.1

How to fix

Upgrade to a fixed version: nodemailer 9.0.1. Check the vendor advisory for mitigations.
