CVE-2026-106072

A flaw in Node.js TLS hostname verification allows a certificate with only a DNS SAN to authenticate an IP endpoint when the client connects using a non-canonical IPv4 spelling, such as 0177.0.0.1, 0x7f.0.0.1, 2130706433 or 127.1. tls.checkServerIdentity did not classify these hosts as IP...

CVE-2026-89134 Subject CN name-constraint check bypassed when non-DNS SAN present

A certificate with no dNSName SAN but another SAN type present e.g. registeredID or iPAddress bypassed the Subject CN dNSName name-constraint check. The CN-as-DNS fallback was gated on cert-subjectCN != NULL && cert-altNames == NULL && !cert-isCA instead of "no dNSName SAN", so an out-of-scope CN...

CVE-2026-89134

The wolfSSL library (version 5.9.2 ) is vulnerable to a bypass of the Subject CN dNSName name-constraint check . This issue arises because the CN-as-DNS fallback was incorrectly gated on the absence of all alternative names (cert->altNames == NULL) rather than specifically checking for the abs...
