- Summary
- CVE-2026-105483 affecting package nodejs 24.21.0-1
- Details
-
A flaw in Node.js TLS hostname verification allows a certificate without a matching IP address SAN to authenticate a connection to an IPv4 address when the host is written with non-ASCII characters, such as fullwidth digits (
１２７.0.0.1).tls.checkServerIdentity()did not recognize such hosts as IP addresses, even though they normalize and resolve to a regular IPv4 address, and matched them against the certificate DNS names and Common Name instead. A certificate containingDNS:127.0.0.1orDNS:*.0.0.1could therefore be accepted for an IP endpoint it was not issued for. This is a regression introduced after the fix for CVE-2026-48618.This vulnerability affects Node.js 26.x and 24.x.
