CVE-2026-42013 2 Gnu, Redhat 15 Gnutls, Discovery, Enterprise Linux and 12 more 2026-07-22 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-2026-42011 1 Redhat 14 Discovery, Enterprise Linux, Enterprise Linux Eus and 11 more 2026-07-22 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-2025-32989 2 Gnu, Redhat 10 Gnutls, Ceph Storage, Discovery and 7 more 2026-06-30 5.3 Medium
A heap-buffer-overread vulnerability was found in GnuTLS in how it handles the Certificate Transparency (CT) Signed Certificate Timestamp (SCT) extension during X.509 certificate parsing. This flaw allows a malicious user to create a certificate containing a malformed SCT extension (OID 1.3.6.1.4.1.11129.2.4.2) that contains sensitive data. This issue leads to the exposure of confidential information when GnuTLS verifies certificates from certain websites when the certificate (SCT) is not checked correctly.
CVE-2015-4000 13 Apple, Canonical, Debian and 10 more 31 Iphone Os, Mac Os X, Safari and 28 more 2026-05-27 3.7 Low
The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue.
CVE-2026-43869 1 Apache 1 Thrift 2026-05-06 7.3 High
Improper Validation of Certificate with Host Mismatch vulnerability in Apache Thrift. This issue affects Apache Thrift: before 0.23.0. Users are recommended to upgrade to version 0.23.0, which fixes the issue.
CVE-2009-2409 4 Gnu, Mozilla, Openssl and 1 more 7 Gnutls, Network Security Services, Openssl and 4 more 2026-04-23 N/A
The Network Security Services (NSS) library before 3.12.3, as used in Firefox; GnuTLS before 2.6.4 and 2.7.4; OpenSSL 0.9.8 through 0.9.8k; and other products support MD2 with X.509 certificates, which might allow remote attackers to spoof certificates by using MD2 design flaws to generate a hash collision in less than brute-force time. NOTE: the scope of this issue is currently limited because the amount of computation required is still large.
CVE-2026-23116 1 Linux 1 Linux Kernel 2026-04-17 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: pmdomain: imx8m-blk-ctrl: Remove separate rst and clk mask for 8mq vpu For i.MX8MQ platform, the ADB in the VPUMIX domain has no separate reset and clock enable bits, but is ungated and reset together with the VPUs. So we can't reset G1 or G2 separately, it may led to the system hang. Remove rst_mask and clk_mask of imx8mq_vpu_blk_ctl_domain_data. Let imx8mq_vpu_power_notifier() do really vpu reset.
CVE-2026-3336 2 Amazon, Aws 3 Aws-lc-sys, Aws Libcrypto, Aws-lc 2026-04-17 7.5 High
Improper certificate validation in PKCS7_verify() in AWS-LC allows an unauthenticated user to bypass certificate chain verification when processing PKCS7 objects with multiple signers, except the final signer. Customers of AWS services do not need to take action. Applications using AWS-LC should upgrade to AWS-LC version 1.69.0.
CVE-2025-52919 2026-04-15 4.3 Medium
In Yealink RPS before 2025-05-26, the certificate upload function does not properly validate certificate content, potentially allowing invalid certificates to be uploaded.
CVE-2024-13956 1 Abb 3 Aspect Enterprise, Matrix Series, Nexus Series 2026-04-15 6.7 Medium
SSL Verification Bypass vulnerabilities exist in ASPECT if administrator credentials become compromisedThis issue affects ASPECT-Enterprise: through 3.*; NEXUS Series: through 3.*; MATRIX Series: through 3.*.
CVE-2025-32057 1 Bosch 1 Infotainment System Ecu 2026-04-15 6.5 Medium
The Infotainment ECU manufactured by Bosch which is installed in Nissan Leaf ZE1 – 2020 uses a Redbend service for over-the-air provisioning and updates. HTTPS is used for communication with the back-end server. Due to usage of the default configuration for the underlying SSL engine, the server root certificate is not verified. As a result, an attacker may be able to impersonate a Redbend backend server using a self-signed certificate. First identified on Nissan Leaf ZE1 manufactured in 2020.
CVE-2025-0309 1 Netskope 1 Netskope 2026-04-15 N/A
An insufficient validation on the server connection endpoint in Netskope Client allows local users to elevate privileges on the system. The insufficient validation allows Netskope Client to connect to any other server with Public Signed CA TLS certificates and send specially crafted responses to elevate privileges.
CVE-2017-13083 1 Akeo 1 Rufus 2026-04-07 N/A
Akeo Consulting Rufus prior to version 2.17.1187 does not adequately validate the integrity of updates downloaded over HTTP, allowing an attacker to easily convince a user to execute arbitrary code
CVE-2025-27377 1 Altium 1 Designer 2026-02-26 5.3 Medium
Altium Designer version 24.9.0 does not validate self-signed server certificates for cloud connections. An attacker capable of performing a man-in-the-middle (MITM) attack could exploit this issue to intercept or manipulate network traffic, potentially exposing authentication credentials or sensitive design data.
CVE-2023-5909 4 Ge, Ptc, Rockwellautomation and 1 more 8 Industrial Gateway Server, Keepserverex, Opc-aggregator and 5 more 2026-02-25 7.5 High

CVE-2025-9293 2 Tp-link, Tp Link 14 Aginet App, Deco App, Festa App and 11 more 2026-02-13 N/A
A vulnerability in the certificate validation logic may allow applications to accept untrusted or improperly validated server identities during TLS communication. An attacker in a privileged network position may be able to intercept or modify traffic if they can position themselves within the communication channel. Successful exploitation may compromise confidentiality, integrity, and availability of application data.
CVE-2026-21228 1 Microsoft 1 Azure Local 2026-02-13 8.1 High
Improper certificate validation in Azure Local allows an unauthorized attacker to execute code over a network.
CVE-2026-0872 1 Thales 1 Safenet Agent For Windows Logon 2026-02-13 N/A

CVE-2026-25160 1 Alistgo 1 Alist 2026-02-13 9.1 Critical
Alist is a file list program that supports multiple storages, powered by Gin and Solidjs. Prior to version 3.57.0, the application disables TLS certificate verification by default for all outgoing storage driver communications, making the system vulnerable to Man-in-the-Middle (MitM) attacks. This enables the complete decryption, theft, and manipulation of all data transmitted during storage operations, severely compromising the confidentiality and integrity of user data. This issue has been patched in version 3.57.0.
