Improper Certificate Validation

Overview Affected versions of this package are vulnerable to Improper Certificate Validation due to insecure default behavior in the idpcertfingerprintvalidator. An attacker can bypass certificate validation by providing any certificate fingerprint, which will be accepted as valid. Remediation...

Improper Certificate Validation

kuma-dp is vulnerable to Improper Certificate Validation. The vulnerability is due to TLS peer verification being disabled when no CA certificate is provided for an HTTPS control plane, which allows an attacker to perform a man-in-the-middle attack and intercept the dataplane authentication token...

Improper Certificate Validation

kumactl is vulnerable to Improper Certificate Validation. The vulnerability is due to TLS certificate verification being disabled when an HTTPS control plane profile is configured without a CA certificate, which allows an attacker to perform a man-in-the-middle attack and intercept API tokens...

CVE-2026-13410: Improper Certificate Validation

Dancer::Plugin::Auth::Google versions before 0.08 for Perl have TLS verification disabled. The default user agent is initialised with SSLverifymode explicitly disabled. An attacker with network man-in-the-middle MITM capability between the Dancer application and googleapis.com can intercept the...

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...

crypto/x509: golang: Go crypto/x509: Denial of Service via inefficient certificate chain validation

A flaw was found in Go's crypto/x509 package. A remote attacker could exploit this by presenting a specially crafted certificate chain containing a large number of policy mappings. This inefficient validation process consumes excessive resources, which can lead to a denial of service DoS for...

Improper Validation of Certificate with Host Mismatch

Overview snowflake-connector-python is a Snowflake Connector for Python Affected versions of this package are vulnerable to Improper Validation of Certificate with Host Mismatch in the TLS certificate verification process. An attacker can intercept sensitive data, tamper with queries, or execute...

CVE-2026-15925 Improper TLS Hostname Verification in Snowflake Connector for Python

Improper TLS hostname verification in Snowflake Connector for Python versions prior to 4.7.1 and 3.18.1 may have allowed a network-positioned attacker to bypass certificate hostname validation on HTTPS connections made by the connector. An attacker with on-path network access could exploit this b...

nodejs: Node.js: Certification validation bypass in TLS host verification

A flaw was found in Node.js. An attacker can exploit a vulnerability in the Transport Layer Security TLS host verification process to bypass certification validation. This bypass could allow an attacker to intercept or alter communications, potentially leading to information disclosure or integri...

erlang: Erlang OTP public_key: Certificate validation bypass allows hostname spoofing

A flaw was found in Erlang OTP publickey. This improper certificate validation vulnerability allows a subordinate Certificate Authority CA with restricted DNS nameConstraints to bypass these restrictions. By issuing a leaf certificate that lacks a Subject Alternative Name SAN but contains a craft...

erlang: Erlang OTP public_key: Certificate chain forgery via improper trust chain validation

A flaw was found in Erlang OTP's publickey module. This vulnerability CWE-295, related to improper certificate validation, allows a non-Certificate Authority CA certificate to be accepted as an intermediate issuer. A remote attacker, holding an end-entity certificate issued by a trusted CA, can...

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...

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...
