CVE-2024-6472 3 Libreoffice, Redhat, The Document Foundation 7 Libreoffice, Enterprise Linux, Rhel Aus and 4 more 2025-12-10 7.8 High
Certificate Validation user interface in LibreOffice allows potential vulnerability. Signed macros are scripts that have been digitally signed by the developer using a cryptographic signature. When a document with a signed macro is opened a warning is displayed by LibreOffice before the macro is executed. Previously if verification failed the user could fail to understand the failure and choose to enable the macros anyway. This issue affects LibreOffice: from 24.2 before 24.2.5.
CVE-2021-25635 2 Libreoffice, Redhat 2 Libreoffice, Enterprise Linux 2025-12-10 5.5 Medium
An Improper Certificate Validation vulnerability in LibreOffice allowed an attacker to self sign an ODF document, with a signature untrusted by the target, then modify it to change the signature algorithm to an invalid (or unknown to LibreOffice) algorithm and LibreOffice would incorrectly present such a signature with an unknown algorithm as a valid signature issued by a trusted person This issue affects LibreOffice: from 7.0 before 7.0.5, from 7.1 before 7.1.1.

CVE-2025-66491 1 Traefik 1 Traefik 2025-12-09 5.9 Medium
Traefik is an HTTP reverse proxy and load balancer. Versions 3.5.0 through 3.6.2 have inverted TLS verification logic in the nginx.ingress.kubernetes.io/proxy-ssl-verify annotation. Setting the annotation to "on" (intending to enable backend TLS certificate verification) actually disables verification, allowing man-in-the-middle attacks against HTTPS backends when operators believe they are protected. This issue is fixed in version 3.6.3.
CVE-2023-5554 1 Linecorp 1 Line 2025-12-09 4.8 Medium
Lack of TLS certificate verification in log transmission of a financial module within LINE client for iOS prior to 13.16.0.
CVE-2025-12943 1 Netgear 4 Rax30, Rax30 Firmware, Raxe300 and 1 more 2025-12-08 7.5 High
Improper certificate validation in firmware update logic in NETGEAR RAX30 (Nighthawk AX5 5-Stream AX2400 WiFi 6 Router) and RAXE300 (Nighthawk AXE7800 Tri-Band WiFi 6E Router) allows attackers with the ability to intercept and tamper traffic destined to the device to execute arbitrary commands on the device. Devices with automatic updates enabled may already have this patch applied. If not, please check the firmware version and update to the latest. Fixed in: RAX30 firmware 1.0.14.108 or later. RAXE300 firmware 1.0.9.82 or later
CVE-2025-12893 3 Apple, Microsoft, Mongodb 3 Macos, Windows, Mongodb 2025-12-05 4.2 Medium
Clients may successfully perform a TLS handshake with a MongoDB server despite presenting a client certificate not aligning with the documented Extended Key Usage (EKU) requirements. A certificate that specifies extendedKeyUsage but is missing extendedKeyUsage = clientAuth may still be successfully authenticated via the TLS handshake as a client. This issue is specific to MongoDB servers running on Windows or Apple as the expected validation behavior functions correctly on Linux systems. Additionally, MongoDB servers may successfully establish egress TLS connections with servers that present server certificates not aligning with the documented Extended Key Usage (EKU) requirements. A certificate that specifies extendedKeyUsage but is missing extendedKeyUsage = serverAuth may still be successfully authenticated via the TLS handshake as a server. This issue is specific to MongoDB servers running on Apple as the expected validation behavior functions correctly on both Linux and Windows systems. This vulnerability affects MongoDB Server v7.0 versions prior to 7.0.26, MongoDB Server v8.0 versions prior to 8.0.16 and MongoDB Server v8.2 versions prior to 8.2.2
CVE-2025-11695 1 Mongodb 2 Rust-driver, Rust Driver 2025-12-04 8 High
When tlsInsecure=False appears in a connection string, certificate validation is disabled. This vulnerability affects MongoDB Rust Driver versions prior to v3.2.5
CVE-2025-62371 2 Amazon, Opensearch 2 Opensearch Data Prepper, Opensearch 2025-12-04 7.4 High
OpenSearch Data Prepper as an open source data collector for observability data. In versions prior to 2.12.2, the OpenSearch sink and source plugins in Data Prepper trust all SSL certificates by default when no certificate path is provided. Prior to this fix, the OpenSearch sink and source plugins would automatically use a trust all SSL strategy when connecting to OpenSearch clusters if no certificate path was explicitly configured. This behavior bypasses SSL certificate validation, potentially allowing attackers to intercept and modify data in transit through man-in-the-middle attacks. The vulnerability affects connections to OpenSearch when the cert parameter is not explicitly provided. This issue has been patched in version 2.12.2. As a workaround, users can add the cert parameter to their OpenSearch sink or source configuration with the path to the cluster's CA certificate.
CVE-2025-11619 1 Devolutions 1 Devolutions Server 2025-12-03 8.8 High
Improper certificate validation when connecting to gateways in Devolutions Server 2025.3.2 and earlier allows attackers in MitM position to intercept traffic.
CVE-2025-32989 2 Gnu, Redhat 9 Gnutls, Ceph Storage, Discovery and 6 more 2025-12-01 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-2025-6032 1 Redhat 3 Enterprise Linux, Openshift, Rhel Eus 2025-11-29 8.3 High
A flaw was found in Podman. The podman machine init command fails to verify the TLS certificate when downloading the VM images from an OCI registry. This issue results in a Man In The Middle attack.
CVE-2024-49369 2 Debian, Icinga 3 Debian Linux, Icinga, Icinga Web 2 2025-11-26 9.8 Critical
Icinga is a monitoring system which checks the availability of network resources, notifies users of outages, and generates performance data for reporting. The TLS certificate validation in all Icinga 2 versions starting from 2.4.0 was flawed, allowing an attacker to impersonate both trusted cluster nodes as well as any API users that use TLS client certificates for authentication (ApiUser objects with the client_cn attribute set). This vulnerability has been fixed in v2.14.3, v2.13.10, v2.12.11, and v2.11.12.
CVE-2025-44018 1 Gl-inet 1 Gl-axt1800 2025-11-26 8.3 High
A firmware downgrade vulnerability exists in the OTA Update functionality of GL-Inet GL-AXT1800 4.7.0. A specially crafted .tar file can lead to a firmware downgrade. An attacker can perform a man-in-the-middle attack to trigger this vulnerability.
CVE-2016-9064 2 Mozilla, Redhat 2 Firefox, Enterprise Linux 2025-11-25 N/A
Add-on updates failed to verify that the add-on ID inside the signed package matched the ID of the add-on being updated. An attacker who could perform a man-in-the-middle attack on the user's connection to the update server and defeat the certificate pinning protection could provide a malicious signed add-on instead of a valid update. This vulnerability affects Firefox ESR < 45.5 and Firefox < 50.
CVE-2025-64434 1 Kubevirt 1 Kubevirt 2025-11-25 4.7 Medium
KubeVirt is a virtual machine management add-on for Kubernetes. Prior to 1.5.3 and 1.6.1, due to the peer verification logic in virt-handler (via verifyPeerCert), an attacker who compromises a virt-handler instance, could exploit these shared credentials to impersonate virt-api and execute privileged operations against other virt-handler instances potentially compromising the integrity and availability of the VM managed by it. This vulnerability is fixed in 1.5.3 and 1.6.1.
CVE-2025-64432 1 Kubevirt 1 Kubevirt 2025-11-25 4.7 Medium
KubeVirt is a virtual machine management add-on for Kubernetes. Versions 1.5.3 and below, and 1.6.0 contained a flawed implementation of the Kubernetes aggregation layer's authentication flow which could enable bypass of RBAC controls. It was discovered that the virt-api component fails to correctly authenticate the client when receiving API requests over mTLS. In particular, it fails to validate the CN (Common Name) field in the received client TLS certificates against the set of allowed values defined in the extension-apiserver-authentication configmap. Failre to validate certain fields in the client TLS certificate may allow an attacker to bypass existing RBAC controls by directly communicating with the aggregated API server, impersonating the Kubernetes API server and its aggregator component. This issue is fixed in versions 1.5.3 and 1.6.1.
CVE-2025-34199 2 Printerlogic, Vasion 4 Vasion Print, Virtual Appliance, Virtual Appliance Application and 1 more 2025-11-25 8.1 High
Vasion Print (formerly PrinterLogic) Virtual Appliance Host versions prior to 22.0.1049 and Application versions prior to 20.0.2786 (VA and SaaS deployments) contain insecure defaults and code patterns that disable TLS/SSL certificate verification for communications to printers and internal microservices. In multiple places, the application sets libcurl/PHP transport options such that CURLOPT_SSL_VERIFYHOST and CURLOPT_SSL_VERIFYPEER are effectively disabled, and environment variables (for example API_*_VERIFYSSL=false) are used to turn off verification for gateway and microservice endpoints. As a result, the client accepts TLS connections without validating server certificates (and, in some cases, uses clear-text HTTP), permitting on-path attackers to perform man-in-the-middle (MitM) attacks. An attacker able to intercept network traffic between the product and printers or microservices can eavesdrop on and modify sensitive data (including print jobs, configuration, and authentication tokens), inject malicious payloads, or disrupt service. This vulnerability has been identified by the vendor as: V-2024-024 — Insecure Communication to Printers & Microservices.
CVE-2025-64685 1 Jetbrains 1 Youtrack 2025-11-21 8.1 High
