{"id":"DEBIAN-CVE-2026-121426","details":"Nodemailer from 3.0.0 before 10.1.4 contains an address parsing vulnerability in addressparser that ends an angle-addr at a '\u003e' inside a quoted local part, comment or domain literal. Attackers can submit addresses that validate as an allowed domain but are delivered to an attacker-controlled domain, bypassing recipient allow lists and disclosing message content.","modified":"2026-11-04T10:00:46.182243903Z","published":"2026-11-03T15:17:33.213Z","upstream":["CVE-2026-121426"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-121426"}],"affected":[{"package":{"name":"node-nodemailer","ecosystem":"Debian:12","purl":"pkg:deb/debian/node-nodemailer?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["10.0.0+~8.0.1-1","10.0.10+~8.0.1-1","10.0.10+~8.0.2-1","10.0.13+~8.0.2-1","10.0.14+~8.0.2-1","10.1.7+~8.0.2-1","6.10.0+~6.4.17-1","6.8.0+~6.4.6-1","6.9.13+~6.4.14-1","6.9.15+~6.4.16-1","6.9.16+~6.4.16-1","6.9.4+~6.4.9-1","6.9.4+~6.4.9-2","6.9.4+~6.4.9-3","6.9.4+~6.4.9-4","7.0.10+~7.0.2-1","7.0.12+~7.0.5-1","7.0.5+~7.0.1-1","7.0.6+~7.0.1-1","7.0.9+~7.0.2-1","7.0.9+~7.0.2-2","8.0.11+~8.0.1-1","8.0.2+~7.0.11-1","8.0.3+~7.0.11-1","8.0.4+~7.0.11-1","8.0.4+~7.0.11-2","9.0.0+~8.0.1-1","9.0.3+~8.0.1-1","9.0.5+~8.0.1-1","9.0.6+~8.0.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-121426.json"}},{"package":{"name":"node-nodemailer","ecosystem":"Debian:13","purl":"pkg:deb/debian/node-nodemailer?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["10.0.0+~8.0.1-1","10.0.10+~8.0.1-1","10.0.10+~8.0.2-1","10.0.13+~8.0.2-1","10.0.14+~8.0.2-1","10.1.7+~8.0.2-1","6.10.0+~6.4.17-1","6.10.0+~6.4.17-1+deb13u1","7.0.10+~7.0.2-1","7.0.12+~7.0.5-1","7.0.5+~7.0.1-1","7.0.6+~7.0.1-1","7.0.9+~7.0.2-1","7.0.9+~7.0.2-2","8.0.11+~8.0.1-1","8.0.2+~7.0.11-1","8.0.3+~7.0.11-1","8.0.4+~7.0.11-1","8.0.4+~7.0.11-2","9.0.0+~8.0.1-1","9.0.3+~8.0.1-1","9.0.5+~8.0.1-1","9.0.6+~8.0.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-121426.json"}},{"package":{"name":"node-nodemailer","ecosystem":"Debian:14","purl":"pkg:deb/debian/node-nodemailer?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["10.0.0+~8.0.1-1","10.0.10+~8.0.1-1","10.0.10+~8.0.2-1","10.0.13+~8.0.2-1","10.0.14+~8.0.2-1","10.1.7+~8.0.2-1","6.10.0+~6.4.17-1","7.0.10+~7.0.2-1","7.0.12+~7.0.5-1","7.0.5+~7.0.1-1","7.0.6+~7.0.1-1","7.0.9+~7.0.2-1","7.0.9+~7.0.2-2","8.0.11+~8.0.1-1","8.0.2+~7.0.11-1","8.0.3+~7.0.11-1","8.0.4+~7.0.11-1","8.0.4+~7.0.11-2","9.0.0+~8.0.1-1","9.0.3+~8.0.1-1","9.0.5+~8.0.1-1","9.0.6+~8.0.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-121426.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:N"}]}
