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...

CVE-2026-72673 Incorrect Authorization in Kibana Leading to Unauthorized Deletion of Synthetics Private Locations

Incorrect Authorization CWE-863 in Kibana can lead to unauthorized deletion of Synthetics private locations via Accessing Functionality Not Properly Constrained by ACLs CAPEC-1. Synthetics private locations can be shared with more than one space, and deleting one removes it from every space it is...

openjdk: Improve certification checking (Oracle CPU 2026-07)

A flaw was found in OpenJDK. OpenJDK can apply two different security meanings to the same wildcard dNSName SAN across certificate policy enforcement and hostname verification. During path validation, DNSName.constrains compares .foo.com and secret.foo.com literally and returns NAMESAMETYPE, so...

tomcat: Apache Tomcat: Misleading security logs due to incorrect control flow

A flaw was found in Apache Tomcat. Due to an always-incorrect control flow implementation, special roles and empty authorization constraints were not accurately included when the effective web.xml configuration was logged. This could lead to a security oversight where administrators might...

tomcat: Apache Tomcat: Security constraint bypass via improper URL encoding in rewrite valve

A flaw was found in Apache Tomcat. This vulnerability, located in the rewrite valve, is due to improper handling of URL encoding hex encoding. A remote attacker could exploit this to bypass security constraints in certain configurations, potentially gaining unauthorized access or performing actio...

EUVD-2026-52699

The non-blocking asynchronous JSON parser in jackson-core does not enforce the maxNumberLength constraint defined in StreamReadConstraints default: 1000 characters. An attacker able to submit JSON to an application that uses the async parser API can supply a number token of arbitrary length,...

Security Bulletin:DNS Name Constraints Validation Issue Fixed in cryptography v46.0.6

Summary 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,...

Improper Certificate Validation

Overview Affected versions of this package are vulnerable to Improper Certificate Validation in the DNSConstraint::matches. An attacker can bypass name constraints by presenting a certificate with a wildcard DNS Subject Alternative Name that is improperly validated, allowing acceptance of...

UBUNTU-CVE-2026-69248

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Prior to 49.0.0, 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's verifier...

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...
