| CVE-2026-96222 | 1 Microsoft | 12 .net, .net Framework, Microsoft Visual Studio 2026 Version 18.10 and 9 more | 2026-10-14 | 7.4 High |
| Improper certificate validation in Active Directory Federation Services (AD FS) allows an unauthorized attacker to perform spoofing over a network. | ||||
| 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-2026-54100 | 1 Redhat | 5 Openshift, Openshift Container Platform, Openshift For Windows Containers and 2 more | 2026-10-14 | 8.3 High |
| A flaw was found in the Windows Machine Config Operator (WMCO) for Red Hat OpenShift Container Platform. WMCO establishes SSH connections to Windows worker nodes without verifying the remote server host key. An adjacent-network attacker who can intercept or redirect WMCO's SSH session can capture WICD and kubelet bootstrap credentials transferred during node configuration, enabling compromise of Windows node identities in the cluster. | ||||

| CVE-2026-97687 | 2 Python, Urllib3 | 2 Urllib3, Urllib3 | 2026-10-13 | 8.1 High |
| urllib3 is an HTTP client library for Python. From 1.26.0 until 2.8.0, the proxy_ssl_context, proxy_assert_hostname, proxy_assert_fingerprint, ssl_context, cert_reqs, verify_mode, use_forwarding_for_https=True, and CERT_NONE configuration paths fail to remain separated because target-server TLS settings are incorrectly applied to the HTTPS proxy connection. The trigger is that an application uses an HTTPS proxy and configures target-server TLS settings that must remain separate from the proxy TLS handshake, including HTTPS forwarding with target-specific identity or credentials. Applying cert_reqs=CERT_NONE can overwrite proxy_ssl_context.verify_mode in place, and the mutation persists so later connections reusing the same context may connect to the HTTPS proxy without certificate verification. The attack mechanism is that an attacker intercepts and impersonates the HTTPS proxy after the effective proxy policy accepts the attacker's certificate. The impact is that the attacker can observe or modify forwarded traffic or receive a target TLS client certificate, while CONNECT tunneling still preserves the separate end-to-end target TLS connection. This issue is fixed in version 2.8.0. | ||||
| CVE-2026-77816 | 1 Ibm | 1 Websphere Application Server Liberty | 2026-10-13 | 6.5 Medium |
| IBM WebSphere Application Server - Liberty 17.0.0.3 through 26.0.0.9 administrative client could allow man-in-the-middle attacks. An attacker could exploit this vulnerability to obtain sensitive information. | ||||
