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,...

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

Summary 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, python-cryptography's verifier accepts which allows escaping outside of the permitted names. PoC !/usr/bin/env python3 """Standalone PoC: pyca's...

CVE-2025-9291

A certification validation weakness exists in communication between affected Omada devices and cloud controllers. Certificate identity verification does not adequately validate that a presented certificate corresponds to the expected cloud controller hostname, which may allow certificate validati...

CVE-2025-9291

The CVE-2025-9291 entry documents a certificate validation weakness in Omada devices communicating with cloud controllers. Specifically, certificate identity verification does not adequately confirm that a presented certificate matches the expected cloud controller hostname, potentially allowing ...

crypto/x509: golang: Go crypto/x509: Certificate validation bypass due to incorrect DNS constraint application

A flaw was found in the crypto/x509 package within Go golang. When verifying a certificate chain, excluded DNS Domain Name System constraints are not correctly applied to wildcard DNS Subject Alternative Names SANs if the case of the SAN differs from the constraint. This oversight could allow an...

crypto/x509: Incorrect enforcement of email constraints in crypto/x509

A certificate validation flaw has been discovered in the golang crypto/x509 module. When verifying a certificate chain which contains a certificate containing multiple email address constraints which share common local portions but different domain portions, these constraints will not be properly...

SUSE CVE-2026-66402

FreeRDP before 3.29.0 affected versions = 3.28.0 contains multiple TLS certificate identity validation weaknesses in tlsverifycertificate, tlsmatchhostname, and x509utilsgetdnsnames. Because FreeRDP performs custom Common Name and DNS SAN string matching instead of using OpenSSL's length-aware...

SUSE CVE-2026-67293

FreeRDP before 3.29.0 affected versions = 3.28.0 contains an improper certificate hostname validation vulnerability. The TLS hostname matcher tlsmatchhostname in libfreerdp/crypto/tls.c treats a wildcard pattern such as .example.com as matching any hostname ending in .example.com, so it incorrect...
