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-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-2026-33542 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-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.
CVE-2026-33308 2 Airtower-luna, Mod Gnutls Project 2 Mod Gnutls, Mod Gnutls 2026-03-25 6.8 Medium
Mod_gnutls is a TLS module for Apache HTTPD based on GnuTLS. Prior to version 0.13.0, code for client certificate verification did not check the key purpose as set in the Extended Key Usage extension. An attacker with access to the private key for a valid certificate issued by a CA trusted for TLS client authentication but designated for a different purpose could have used that certificate to improperly access resources requiring TLS client authentication. Server configurations that do not use client certificates (`GnuTLSClientVerify ignore`, the default) are not affected. The problem has been fixed in version 0.13.0 by rewriting certificate verification to use `gnutls_certificate_verify_peers()`, and requiring key purpose id-kp-clientAuth (also known as `tls_www_client` in GnuTLS) by default if the Extended Key Usage extension is present. The new `GnuTLSClientKeyPurpose` option allows overriding the expected key purpose if needed (please see the manual for details). Behavior for certificates without an Extended Key Usage extension is unchanged. If dedicated (sub-)CAs are used for issuing TLS client certificates only (not for any other purposes) the issue has no practical impact.
