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...

Node.js Node encryption issues vulnerability

Versions 22.23.3 and earlier of Node.js, 24.22.0 and earlier, and 26.12.0 and earlier contain an encryption vulnerability stemming from a flaw in TLS hostname validation: when the host is an invalid IPv4 address with a leading zero e.g., 0127.0.0.1, tls.checkServerIdentity interprets the leading...

Node.js Node encryption issues vulnerability

Node.js versions 24.22.0 and earlier, as well as 26.12.0 and earlier, contain an encryption-related vulnerability. This vulnerability arises because TLS hostname validation fails to treat hostnames containing non-ASCII characters—such as full-width digits—as IP addresses; instead, it matches them...
