CVE-2026-29140 1 Seppmail 1 Seppmail Secure Email Gateway 2026-04-02 N/A
SEPPmail Secure Email Gateway before version 15.0.3 allows an attacker to cause attacker-controlled certificates to be used for future encryption to a victim by adding the certificates to S/MIME signatures.
CVE-2026-20042 2026-04-02 6.5 Medium
A vulnerability in the configuration backup feature of Cisco Nexus Dashboard could allow an attacker who has the encryption password and access to Full or Config-only backup files to access sensitive information. This vulnerability exists because authentication details are included in the encrypted backup files. An attacker with a valid backup file and encryption password from an affected device could decrypt the backup file. The attacker could then use the authentication details in the backup file to access internal-only APIs on the affected device. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system as the root user.
CVE-2025-9293 2 Tp-link, Tp Link 24 Aginet, Aginet App, Deco and 21 more 2026-04-01 8.1 High
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-2026-25834 2026-04-01 6.5 Medium
Mbed TLS v3.3.0 up to 3.6.5 and 4.0.0 allows Algorithm Downgrade.
CVE-2025-70029 2 Sunbird, Sunbird-ed 2 Sunbirded-portal, Sunbirded-portal 2026-04-01 7.5 High
An issue in Sunbird-Ed SunbirdEd-portal v1.13.4 allows attackers to obtain sensitive information. The application disables TLS/SSL certificate validation by setting 'rejectUnauthorized': false in HTTP request options
CVE-2026-32884 1 Randombit 1 Botan 2026-04-01 5.9 Medium
Botan is a C++ cryptography library. Prior to version 3.11.0, during processing of an X.509 certificate path using name constraints which restrict the set of allowable DNS names, if no subject alternative name is defined in the end-entity certificate Botan would check that the CN was allowed by the DNS name constraints, even though this check is technically not required by RFC 5280. However this check failed to account for the possibility of a mixed-case CN. Thus a certificate with CN=Sub.EVIL.COM and no subject alternative name would bypasses an excludedSubtrees constraint for evil.com because the comparison is case-sensitive. This issue has been patched in version 3.11.0.
CVE-2026-34073 1 Pyca 1 Cryptography 2026-04-01 3.7 Low
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-2026-32794 1 Apache 1 Airflow Provider For Databricks 2026-04-01 4.8 Medium
Improper Certificate Validation vulnerability in Apache Airflow Provider for Databricks. Provider code did not validate certificates for connections to Databricks back-end which could result in a man-of-a-middle attack that traffic is intercepted and manipulated or credentials exfiltrated w/o notice. This issue affects Apache Airflow Provider for Databricks: from 1.10.0 before 1.12.0. Users are recommended to upgrade to version 1.12.0, which fixes the issue.
CVE-2026-4370 2026-04-01 10 Critical
A vulnerability was identified in Juju from version 3.2.0 until 3.6.19 and from version 4.0 until 4.0.4, where the internal Dqlite database cluster fails to perform proper TLS client and server authentication. Specifically, the Juju controller's database endpoint does not validate client certificates when a new node attempts to join the cluster. An unauthenticated attacker with network reachability to the Juju controller's Dqlite port can exploit this flaw to join the database cluster. Once joined, the attacker gains full read and write access to the underlying database, allowing for total data compromise.
CVE-2026-33542 2 Linuxcontainers, Lxc 2 Incus, Incus 2026-03-31 4.8 Medium
Incus is a system container and virtual machine manager. Prior to version 6.23.0, a lack of validation of the image fingerprint when downloading from simplestreams image servers opens the door to image cache poisoning and under very narrow circumstances exposes other tenants to running attacker controlled images rather than the expected one. Version 6.23.0 patches the issue.
CVE-2025-15612 1 Wazuh 1 Wazuh Provisioning Scripts 2026-03-31 4.8 Medium
Wazuh provisioning scripts and Dockerfiles contain an insecure transport vulnerability where curl is invoked with the -k/--insecure flag, disabling SSL/TLS certificate validation. Attackers with network access can perform man-in-the-middle attacks to intercept and modify downloaded dependencies or code during the build process, leading to remote code execution and supply chain compromise.
CVE-2026-4396 1 Devolutions 1 Hub Reporting Service 2026-03-30 8.3 High
Improper certificate validation in Devolutions Hub Reporting Service 2025.3.1.1 and earlier allows a network attacker to perform a man-in-the-middle attack via disabled TLS certificate verification.
CVE-2026-4434 1 Devolutions 2 Devolutions Server, Server 2026-03-30 8.1 High
Improper certificate validation in the PAM propagation WinRM connections allows a network attacker to perform a man-in-the-middle attack via disabled TLS certificate verification.
CVE-2026-33896 1 Digitalbazaar 1 Forge 2026-03-30 7.4 High
Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.4.0, `pki.verifyCertificateChain()` does not enforce RFC 5280 basicConstraints requirements when an intermediate certificate lacks both the `basicConstraints` and `keyUsage` extensions. This allows any leaf certificate (without these extensions) to act as a CA and sign other certificates, which node-forge will accept as valid. Version 1.4.0 patches the issue.
CVE-2019-25652 1 Ubiquiti 1 Unifi Network Controller 2026-03-30 7.5 High
UniFi Network Controller before version 5.10.22 and 5.11.x before 5.11.18 contains an improper certificate verification vulnerability that allows adjacent network attackers to conduct man-in-the-middle attacks by presenting a false SSL certificate during SMTP connections. Attackers can intercept SMTP traffic and obtain credentials by exploiting the insecure SSL host verification mechanism in the SMTP certificate validation process.
CVE-2026-33248 2 Linuxfoundation, Nats 2 Nats-server, Nats Server 2026-03-27 4.2 Medium
NATS-Server is a High-Performance server for NATS.io, a cloud and edge native messaging system. Prior to versions 2.11.15 and 2.12.6, when using mTLS for client identity, with `verify_and_map` to derive a NATS identity from the client certificate's Subject DN, certain patterns of RDN would not be correctly enforced, allowing for authentication bypass. This does require a valid certificate from a CA already trusted for client certificates, and `DN` naming patterns which the NATS maintainers consider highly unlikely. So this is an unlikely attack. Nonetheless, administrators who have been very sophisticated in their `DN` construction patterns might conceivably be impacted. Versions 2.11.15 and 2.12.6 contain a fix. As a workaround, developers should review their CA issuing practices.
CVE-2026-28755 1 F5 2 Nginx Open Source, Nginx Plus 2026-03-27 5.4 Medium
NGINX Plus and NGINX Open Source have a vulnerability in the ngx_stream_ssl_module module due to the improper handling of revoked certificates when configured with the ssl_verify_client on and ssl_ocsp on directives, allowing the TLS handshake to succeed even after an OCSP check identifies the certificate as revoked.   Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
CVE-2025-7390 1 Softing 4 Edgeaggregator, Edgeconnector, Opc and 1 more 2026-03-27 9.1 Critical
A malicious client can bypass the client certificate trust check of an opc.https server when the server endpoint is configured to allow only secure communication.
CVE-2026-1531 1 Redhat 4 Satellite, Satellite Capsule, Satellite Maintenance and 1 more 2026-03-27 8.1 High
A flaw was found in foreman_kubevirt. When configuring the connection to OpenShift, the system disables SSL verification if a Certificate Authority (CA) certificate is not explicitly set. This insecure default allows a remote attacker, capable of intercepting network traffic between Satellite and OpenShift, to perform a Man-in-the-Middle (MITM) attack. Such an attack could lead to the disclosure or alteration of sensitive information.
CVE-2026-1530 1 Redhat 4 Satellite, Satellite Capsule, Satellite Maintenance and 1 more 2026-03-26 8.1 High
A flaw was found in fog-kubevirt. This vulnerability allows a remote attacker to perform a Man-in-the-Middle (MITM) attack due to disabled certificate validation. This enables the attacker to intercept and potentially alter sensitive communications between Satellite and OpenShift, resulting in information disclosure and data integrity compromise.
