EUVD-2026-26403

A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of nameConstraints labels, specifically for dNSName DNS or rfc822Name email constraints within excludedSubtrees or permittedSubtrees. A remote attacker can exploit this by crafting a leaf...

CVE-2026-3833 Gnutls: gnutls: policy bypass due to case-sensitive nameconstraints comparison

A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of nameConstraints labels, specifically for dNSName DNS or rfc822Name email constraints within excludedSubtrees or permittedSubtrees. A remote attacker can exploit this by crafting a leaf...

PowerDNS Authoritative Server 注入漏洞

The PowerDNS Authoritative Server is a DNS server developed by the Dutch company PowerDNS. There is an injection vulnerability in the PowerDNS Authoritative Server, which stems from incomplete escape sequences in LDAP queries when 8bit-dns is enabled, allowing users to query internal domain...

BIT-GOLANG-2026-33810 Case-sensitive excludedSubtrees name constraints cause Auth Bypass in crypto/x509

When verifying a certificate chain containing excluded DNS constraints, these constraints are not correctly applied to wildcard DNS SANs which use a different case than the constraint. This only affects validation of otherwise trusted certificate chains, issued by a root CA in the...

CVE-2026-33810

CVE-2026-33810 affects the Go crypto/x509 certificate chain validation. The issue occurs when verifying a chain with excluded DNS constraints: constraints are not consistently applied to wildcard DNS SANs if the SANs’ case differs from the constraint, which can affect validation of otherwise trus...

PYSEC-2026-35

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Prior to version 46.0.6, DNS name constraints were only validated against SANs within child certificates, and not the "peer name" presented during each validation. Consequently, cryptography...
