A flaw in Node.js TLS hostname verification can cause a server certificate to be validated against a different IP address than the one the client connected to, when the host is a non-canonical IPv4 literal with a leading zero, such as
0127.0.0.1.tls.checkServerIdentity()normalizes the host following the WHATWG URL rules, which read a leading-zero octet as octal (0127.0.0.1becomes87.0.0.1), while the connection is made through the operating system resolver, which on some platforms such as macOS reads it as decimal (127.0.0.1). A server at the connected address can then be authenticated with a certificate issued for another IP address.This vulnerability affects Node.js 26.x, 24.x, and 22.x.
