CVE-2026-93600 rustls webpki Name Constraints URI Validation Bypass

rustls-webpki rustls/webpki versions 0.101.0 through 0.103.11 and 0.104.0-alpha releases before 0.104.0-alpha.6 ignore X.509 name constraints that apply to URI names, causing such constraints to be accepted rather than enforced. Because name constraints are restrictions on otherwise properly issu...

python-cryptography: python-cryptography: python-cryptography verifier accepts wildcard DNS names allowing escape from permittedSubtrees

A flaw was found in python-cryptography. This vulnerability arises from incorrect handling of wildcard Domain Name System DNS names during certificate validation. Specifically, the verifier may accept a certificate with a broad wildcard DNS name e.g., .example.com even when a more restrictive nam...

netty: Netty: High integrity impact due to improper DNS domain name constraint enforcement

A flaw was found in Netty. Netty's DNS Domain Name System codec does not properly enforce domain name constraints as defined in RFC 1035 during both encoding and decoding processes. This vulnerability allows a remote attacker to exploit the decoder using malicious DNS responses or exploit the...

CVE-2026-69248

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. In versions 45.0.0 through 48.0.0, if an intermediate constrained CA permits the DNS name foo.example.com, and the leaf certificate has a wildcard in its DNS SAN of .example.com,...
