CVE-2026-19377 2026-10-15 N/A
Improper certificate validation in the tunnel handshake in Cato Client allows a man-in-the-middle attacker to impersonate a Cato Point of Presence (PoP) server and intercept or modify tunnel traffic.
CVE-2026-109423 1 Netease 1 Netease Cloud Music For Windows 2026-10-15 7.4 High
NetEase Cloud Music client for Windows (cloudmusic.exe) versions 3.1.38 and 3.1.39.205426 contains a TLS certificate validation vulnerability that allows a network-adjacent attacker to intercept and decrypt HTTPS traffic by failing to validate the server certificate chain, verify the hostname, or consult any Windows certificate trust store. Attackers can perform a man-in-the-middle attack using a rogue certificate authority to decrypt traffic, capture the MUSIC_U session credential sent in authenticated API requests, and modify server responses in transit, enabling account takeover and transport-layer response forgery.
CVE-2024-8096 4 Curl, Debian, Haxx and 1 more 16 Curl, Debian Linux, Curl and 13 more 2026-10-15 6.5 Medium
When curl is told to use the Certificate Status Request TLS extension, often referred to as OCSP stapling, to verify that the server certificate is valid, it might fail to detect some OCSP problems and instead wrongly consider the response as fine. If the returned status reports another error than 'revoked' (like for example 'unauthorized') it is not treated as a bad certficate.
CVE-2024-2379 4 Apple, Haxx, Netapp and 1 more 21 Macos, Curl, Active Iq Unified Manager and 18 more 2026-10-15 6.3 Medium
libcurl skips the certificate verification for a QUIC connection under certain conditions, when built to use wolfSSL. If told to use an unknown/bad cipher or curve, the error path accidentally skips the verification and returns OK, thus ignoring any certificate problems.
CVE-2026-84418 1 Ibm 1 Datastage On Cloud Pak For Data 2026-10-14 7.4 High
IBM DataStage on Cloud Pak for Data 5.4.0.0 can allow a man-in-the-middle attacker to present a forged TLS certificate, intercept the connection, and capture the IAM bearer Authorization header automatically attached by the session adapter. The captured token grants full platform-scope tenant API access, enabling the attacker to read and manipulate the victim's DataStage projects, flows, assets, and pipeline definitions. This is client-side SDK code running on the user's own machine, so exploitation requires an external network interceptor rather than a co-tenant in the shared cluster.
CVE-2015-2625 2 Oracle, Redhat 7 Jdk, Jre, Jrockit and 4 more 2026-10-14 N/A
Unspecified vulnerability in Oracle Java SE 6u95, 7u80, and 8u45; JRockit R28.3.6; and Java SE Embedded 7u75 and 8u33 allows remote attackers to affect confidentiality via vectors related to JSSE.
CVE-2023-0466 2 Openssl, Redhat 4 Openssl, Enterprise Linux, Jboss Core Services and 1 more 2026-10-14 5.3 Medium
The function X509_VERIFY_PARAM_add0_policy() is documented to implicitly enable the certificate policy check when doing certificate verification. However the implementation of the function does not enable the check which allows certificates with invalid or incorrect policies to pass the certificate verification. As suddenly enabling the policy check could break existing deployments it was decided to keep the existing behavior of the X509_VERIFY_PARAM_add0_policy() function. Instead the applications that require OpenSSL to perform certificate policy check need to use X509_VERIFY_PARAM_set1_policies() or explicitly enable the policy check by calling X509_VERIFY_PARAM_set_flags() with the X509_V_FLAG_POLICY_CHECK flag argument. Certificate policy checks are disabled by default in OpenSSL and are not commonly used by applications.
CVE-2023-0465 2 Openssl, Redhat 4 Openssl, Enterprise Linux, Jboss Core Services and 1 more 2026-10-14 5.3 Medium
Applications that use a non-default option when verifying certificates may be vulnerable to an attack from a malicious CA to circumvent certain checks. Invalid certificate policies in leaf certificates are silently ignored by OpenSSL and other certificate policy checks are skipped for that certificate. A malicious CA could use this to deliberately assert invalid certificate policies in order to circumvent policy checking on the certificate altogether. Policy processing is disabled by default but can be enabled by passing the `-policy' argument to the command line utilities or by calling the `X509_VERIFY_PARAM_set1_policies()' function.
CVE-2023-0464 2 Openssl, Redhat 4 Openssl, Enterprise Linux, Jboss Core Services and 1 more 2026-10-14 7.5 High
A security vulnerability has been identified in all supported versions of OpenSSL related to the verification of X.509 certificate chains that include policy constraints. Attackers may be able to exploit this vulnerability by creating a malicious certificate chain that triggers exponential use of computational resources, leading to a denial-of-service (DoS) attack on affected systems. Policy processing is disabled by default but can be enabled by passing the `-policy' argument to the command line utilities or by calling the `X509_VERIFY_PARAM_set1_policies()' function.
CVE-2026-42013 2 Gnu, Redhat 17 Gnutls, Cert Manager, Discovery and 14 more 2026-10-14 8.2 High
A flaw was found in gnutls. When validating certificates, an oversized Subject Alternative Name (SAN) could cause the validation process to incorrectly fall back to checking the Common Name (CN) field. This could allow a remote attacker to bypass proper certificate validation, potentially leading to spoofing or man-in-the-middle attacks.
CVE-2026-42012 2 Gnu, Redhat 17 Gnutls, Cert Manager, Discovery and 14 more 2026-10-14 7.1 High
A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted certificate that contains Uniform Resource Identifier (URI) or Service (SRV) Subject Alternative Names (SANs). This could cause the certificate validation process to incorrectly fall back to checking DNS hostnames against the Common Name (CN), potentially allowing the attacker to spoof legitimate services or intercept sensitive information.
CVE-2026-42011 1 Redhat 16 Cert Manager, Discovery, Enterprise Linux and 13 more 2026-10-14 7.4 High
A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities (CAs) only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate validation. This bypass could lead to the acceptance of invalid certificates, potentially enabling spoofing or man-in-the-middle attacks against affected systems.
CVE-2026-87425 1 Broadcom 1 Brocade Active Support Connectivity Gateway 2026-10-14 6.8 Medium
An unauthenticated remote attacker can modify the TLS client trust store in Brocade ASCG versions before 3.5.0. By supplying an unauthorized Certificate Authority (CA) certificate to an unauthenticated management interface, the attacker can cause the system to trust unauthorized certificates, potentially enabling Man-in-the-Middle (MITM) attacks against outbound communications with managed switches and peer nodes.
CVE-2026-83926 1 Microsoft 11 Windows 10 1809, Windows 10 21h2, Windows 10 22h2 and 8 more 2026-10-14 4.4 Medium
Improper certificate validation in Windows Hello allows an authorized attacker to bypass a security feature locally.
CVE-2026-34073 2 Cryptography.io, Pyca 2 Cryptography, Cryptography 2026-10-14 5.3 Medium
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 would allow a peer named bar.example.com to validate against a wildcard leaf certificate for *.example.com, even if the leaf's parent certificate (or upwards) contained an excluded subtree constraint for bar.example.com. This issue has been patched in version 46.0.6.
CVE-2022-27782 4 Debian, Haxx, Redhat and 1 more 4 Debian Linux, Curl, Enterprise Linux and 1 more 2026-10-14 7.5 High
libcurl would reuse a previously created connection even when a TLS or SSHrelated option had been changed that should have prohibited reuse.libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse if one of them matches the setup. However, several TLS andSSH settings were left out from the configuration match checks, making themmatch too easily.
