| CVE-2026-96222 | 3 Apple, Linux, Microsoft | 21 Macos, Linux Kernel, .net and 18 more | 2026-10-22 | N/A | 7.4 HIGH |

| Improper certificate validation in .NET Framework allows an unauthorized attacker to bypass a security feature over a network. | |||||
| CVE-2026-50578 | 2026-10-22 | N/A | 7.5 HIGH | ||
| ePA 3.x Integration implements the authorization workflow and writes Medical Information Objects to Germany's electronic patient record. Prior to 1.3.0, ePA 3.x Integration disables TLS certificate verification for both ePA connections in app/vau/VAUProtokoll.py and Konnektor connections in app/konnektor/Konnektor.py. A network-positioned attacker can present an arbitrary certificate, terminate the TLS connection, and intercept ePA traffic. The VAU protocol does not provide an effective fallback because its application-layer certificate validation is also broken in affected versions. The Konnektor session uses self.session.verify set to False while the client authenticates with self.session.cert, so an attacker impersonating the Konnektor can receive the client's mutual TLS certificate exchange and observe smartcard operations. This issue is fixed in version 1.3.0. | |||||
| CVE-2026-63336 | 2026-10-22 | N/A | N/A | ||
| The RabbitMQ Java client library allows Java and JVM-based applications to connect to and interact with RabbitMQ nodes. Prior to 5.33.0, com.rabbitmq.client.ConnectionFactory.useSslProtocol() and ConnectionFactory.useSslProtocol(String) configure com.rabbitmq.client.TrustEverythingTrustManager and leave hostname verification disabled, causing arbitrary server certificates, including self-signed certificates, to be accepted. A network attacker able to intercept a TLS connection can impersonate the RabbitMQ broker, read protected AMQP traffic, and modify traffic without certificate or hostname validation. The fix changes the production TLS helpers to use the JVM default trust store and enables hostname verification, while retaining an explicitly named development-only no-verification helper. This issue is fixed in version 5.33.0. | |||||
| CVE-2026-52723 | 2026-10-22 | N/A | 9.1 CRITICAL | ||
| ePA 3.x Integration implements the authorization workflow and writes Medical Information Objects to Germany's electronic patient record. Prior to 1.3.0, ePA 3.x Integration performs VAU server certificate validation in app/vau/VAUProtokoll.py without anchoring the signed_vau_server_pub_keys and AUT_VAU_CertData certificate path to independent trusted material. A network-positioned attacker between the DiGA backend and the ePA system can intercept the VAU handshake, supply attacker-controlled certificate and key material, and satisfy the circular trust relationship. Because TLS certificate verification is also disabled in affected versions, no independent server-authentication layer prevents the attack. The attacker can impersonate the VAU server, control the negotiated session keys, and read or modify all encrypted VAU traffic. This issue is fixed in version 1.3.0. | |||||
| CVE-2026-114220 | 2026-10-22 | N/A | 9.1 CRITICAL | ||
| NT OneAPP developed by NewType Infortech has an Improper Certificate Validation vulnerability. Unauthenticated network-adjacent attackers can perform a man-in-the-middle attack by failing to validate the server certificate and the hostname, thereby intercepting or modifying communications between the application and the server. | |||||
| CVE-2026-114047 | 2026-10-22 | N/A | 6.8 MEDIUM | ||
| FreeRDP from 2.0.0 before 3.32.0 contains an improper certificate validation vulnerability in its proxy that accepts untrusted target TLS certificates when no verification module is configured. Network-positioned attackers can intercept the proxy's outbound connection and present a self-signed, wrong-hostname certificate to impersonate the RDP target and receive proxied session data. | |||||

| CVE-2026-113470 | 2026-10-21 | N/A | 5.4 MEDIUM | ||
| Cryptographic issue in the Security Block-lists, Allow-lists, and other State component. This vulnerability was fixed in Firefox 158.0.1, Firefox ESR 153.5.1, Firefox ESR 115.43.1, Thunderbird 158.0.1, Thunderbird 153.5.1, and Firefox 158.0.2. | |||||
| CVE-2026-84975 | 1 Teluu | 1 Pjsip | 2026-10-20 | N/A | 7.4 HIGH |
| PJSIP is a free and open source multimedia communication library written in C. In 2.17 and earlier, the OpenSSL and GnuTLS backends in pjlib/src/pj/ssl_sock_ossl.c and pjlib/src/pj/ssl_sock_gtls.c copy DNS SubjectAltName values with string functions that recalculate their length and truncate an embedded NUL byte. With server verification enabled through --tls-verify-server for the PJSIP TLS/SIPS transport, a certificate containing a DNS SubjectAltName formed from the target hostname prefix followed by an embedded NUL and an attacker-controlled suffix can therefore be accepted for the prefix hostname. An attacker who possesses such a certificate from a trusted issuer and can intercept the connection can impersonate the target server, complete the SIP session, and receive REGISTER credentials. The mbedTLS backend is not affected because it preserves the explicit string length. No fixed version is available as of this review. | |||||
| CVE-2026-35560 | 4 Amazon, Apple, Linux and 1 more | 4 Athena Odbc, Macos, Linux Kernel and 1 more | 2026-10-20 | N/A | 7.4 HIGH |
| Improper certificate validation in the identity provider connection components in Amazon Athena ODBC driver before 2.1.0.0 might allow a man-in-the-middle threat actor to intercept authentication credentials due to insufficient default transport security when connecting to identity providers. This only applies to connections with external identity providers and does not apply to connections with Athena. To remediate this issue, users should upgrade to version 2.1.0.0. | |||||
| CVE-2026-15554 | 2026-10-20 | N/A | 7.4 HIGH | ||
| the Undertow AJP listener honours forged ssl_cert and is_ssl AJP attributes without requiring any shared-secret authentication. This enables an unauthenticated attacker with direct TCP access to port 8009 to bypass CLIENT-CERT authentication by injecting a forged X.509 certificate via the AJP protocol. | |||||
| CVE-2026-67270 | 1 Dell | 1 Container Storage Modules | 2026-10-20 | N/A | 8.2 HIGH |
| Dell Container Storage Modules (CSM) versions prior to 1.18.0, contains an Improper Certificate Validation vulnerability in the proxy-server component. An unauthenticated adjacent network attacker could potentially exploit this vulnerability, leading to information exposure of storage backend administrator credentials. | |||||

| CVE-2025-36290 | 1 Ibm | 1 Integrated Analytics System | 2026-10-19 | N/A | 5.9 MEDIUM |
| IBM Integrated Analytics System 1.0.0.0 through 1.0.31.0 does not validate or improperly validates TLS certificate validation, which could allow an attacker to obtain sensitive information using man in the middle techniques. | |||||
| CVE-2025-23390 | 2026-10-19 | N/A | 6.3 MEDIUM | ||
| A vulnerability has been identified within Fleet where, by default, Fleet will automatically trust a remote server’s certificate when connecting through SSH if the certificate isn’t set in the `known_hosts` file. This could allow the execution of a man-in-the-middle (MitM) attack against Fleet. In case the server that is being connected to has a trusted entry in the known_hosts file, then Fleet will correctly check the authenticity of the presented certificate. | |||||

| OpenTelemetry opentelemetry-exporter-otlp-proto-http 1.5.0 before 1.45.0 contains an improper certificate validation vulnerability that disables TLS verification when OTEL_EXPORTER_OTLP_CERTIFICATE variables are empty strings. Man-in-the-middle attackers can impersonate the collector to read or alter exported traces, metrics, and logs, including authentication headers from OTEL_EXPORTER_OTLP_HEADERS. | |||||
