{"id":"CVE-2026-92595","summary":"Nodemailer before 9.1.1 Security Sandbox Bypass via resolveContent","details":"Nodemailer (npm package `nodemailer`) versions 9.1.0 and earlier do not honor the `disableFileAccess` and `disableUrlAccess` sandbox options when message content is resolved through the public plugin API `MailMessage.resolveContent()` using the documented legacy three-argument signature `resolveContent(data, key, callback)`. Because `shared.resolveContent()` normalizes the missing `options` argument to an empty object, the message-level flags copied into `mail.data` by the MailMessage constructor are discarded, and `resolveContentValue()` skips both access-control checks, reaching `nmfetch(url)` or `fs.createReadStream(path)`. As a result, plugin or application code that resolves untrusted message content (html, text, attachment `path` or `href`) via this API can be induced to read arbitrary local files or issue outbound HTTP(S) requests (server-side request forgery), bypassing the sandbox the application enabled. The internal paths used by `transporter.sendMail()` (`resolveAll()`, `_convertDataImages()`, and the MIME streaming path) are not affected. Fixed in version 9.1.1.","aliases":["GHSA-8m3c-c648-2xjj"],"modified":"2026-09-18T03:30:48.778193899Z","published":"2026-09-16T21:47:00.171Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92595.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-73"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/92xxx/CVE-2026-92595.json"},{"type":"ADVISORY","url":"https://github.com/nodemailer/nodemailer/security/advisories/GHSA-8m3c-c648-2xjj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-92595"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/nodemailer-before-9.1.1-security-sandbox-bypass-via-resolvecontent"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nodemailer/nodemailer","events":[{"introduced":"0"},{"fixed":"ad4513f2a179e0484f9c95948211c186ba3ce7c9"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"0"},{"fixed":"9.1.1"}]}}],"versions":["v9.1.0","v9.0.6","v9.0.5","v9.0.4","v9.0.3","v9.0.2","v9.0.1","v9.0.0","v8.0.11","v8.0.10","v8.0.9","v8.0.8","v8.0.7","v8.0.6","v8.0.5","v8.0.4","v8.0.3","v8.0.2","v8.0.1","v8.0.0","v7.0.13","v7.0.12","v7.0.11","v7.0.10","v7.0.9","v7.0.7","v7.0.6","v7.0.5","v6.9.16","v6.9.15","v6.9.14","v6.9.13","v6.9.10","v6.9.8","v6.9.7","v6.9.6","v6.9.5","v6.9.4","v6.9.3","v6.9.2","v6.9.1","v6.9.0","v6.8.0","v6.7.8","v6.7.7","v6.7.6","v6.7.5","v6.7.4","v6.7.3","v6.7.2","v6.7.1","v6.7.0","v6.6.5","v6.6.4","v6.6.3","v6.6.1","v6.6.0","v6.5.0","v6.4.18","v6.4.17","v6.4.16","v6.4.15","v6.4.14","v6.4.13","v6.4.12","v6.4.11","v6.4.10","v6.4.8","v6.4.7","v6.4.6","v6.4.5","v6.4.4","v6.4.3","v6.4.2","v6.4.1","v6.4.0","v6.3.1","v6.3.0","v6.2.1","v6.2.0","v6.1.1","v6.1.0","v6.0.0","v5.1.1","v5.1.0","v5.0.1","v5.0.0","v4.7.0","v4.6.8","v4.6.7","v4.6.6","v4.6.5","v4.6.4","v4.6.3","v4.6.2","v4.6.1","v4.6.0","v4.5.0","v4.4.2","v4.4.1","v4.4.0","v4.3.1","v4.3.0","v4.2.0","v4.1.3","v4.1.2","v4.1.1","v4.1.0","v4.0.1","v4.0.0","v3.1.8","v3.1.7","v3.1.6","v3.1.5","v3.1.4","v3.1.3","v3.1.2","v3.1.1","v3.1.0","v3.0.2","v3.0.1","v3.0.0","v2.7.2","v2.7.1","v2.7.0","v2.6.4","v2.6.3","v2.6.2","v2.6.1","v2.6.0","v2.5.0","v2.4.2","v2.4.1","v2.4.0","v2.3.2","v2.3.2-gpgtest.0","v2.3.1","v2.3.0","v2.2.1","v2.2.0","v2.1.0","v2.0.0","v1.11.0","v1.10.0","v1.9.0","v1.8.0","v1.7.0","v1.6.0","v1.5.0","v1.4.0","v1.3.4","v1.3.3","v1.3.2","v1.3.1","v1.3.0","v1.2.2","v1.2.1","v1.2.0","v1.1.2","v1.1.1","v1.1.0","v1.0.4","v1.0.3","v1.0.2","v1.0.1","v1.0.0","v0.7.1","v0.7.0","v0.6.5","v0.6.4","v0.6.3","v0.6.2","v0.6.1","v0.6.0","v0.5.15","v0.5.14","v0.5.13","v0.5.12","v0.5.11","v0.5.9","v0.5.8","v0.5.7","v0.5.6","v0.5.5","v0.5.4","v0.5.3","v0.5.2","v0.5.1","v0.5.0","v0.4.4","v0.4.3","v0.4.2","v0.4.1","v0.4.0","v0.3.45","v0.3.44","v0.3.43","v0.3.42","v0.3.41","v0.3.40","v0.3.39","v0.3.38","v0.3.37","v0.3.35","v0.3.34","v0.3.33","v0.3.32","v0.3.31","v0.3.30","v0.3.29","v0.3.28","v0.3.27","v0.3.26","v0.3.25","v0.3.22","v0.3.21","v0.3.20","v0.3.19","v0.3.18","v0.3.17","v0.3.16","v0.3.15","v0.3.14","v0.3.13","v0.3.12","v0.3.11","v0.3.10","v0.3.9","v0.3.8","v0.3.7","v0.3.6","v0.3.5","v0.3.4","v0.3.3","v0.3.2","v0.3.1","v0.3.0","v0.2.4","v0.2.3","v0.2.2","v0.2.0","v0.1.24","v0.1.23","v0.1.22","v0.1.21","v0.1.20","v0.1.19","v0.1.17","v0.1.16","v0.1.15","v0.1.14","v0.1.13","v0.1.12","v0.1.10","v0.1.9","v0.1.8","v0.1.7","v0.1.6","v0.1.5","v0.1.4","v0.1.3","v0.1.2","v0.1.1","v0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-92595.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
