CVE-2026-48618 is an authentication-bypass vulnerability in Node.js TLS hostname handling. Unicode dot separators can be normalized differently by hostname resolution and TLS certificate hostname verification. This inconsistency can alter the effective label depth used during wildcard matching, allowing a certificate to satisfy hostname verification when it should not. The vulnerability affects supported Node.js 22, 24, and 26 release lines prior to their respective fixed releases.
