CVE-2026-82659 (GCVE-0-2026-82659)

Vulnerability from cvelistv5 – Published: 2026-08-31 08:46 – Updated: 2026-08-31 18:52

Title

nodemailer before 9.0.1 File Read and SSRF via raw option

Summary

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.
