CVE-2026-84032 1 Ibm 1 Guardium Data Protection 2026-10-08 5.6 Medium
IBM Guardium Data Protection 12.2.2 could allow a remote attacker to conduct a man-in-the-middle attack due to improper certificate validation.
CVE-2026-95208 1 Wolfssl 1 Wolfssl 2026-10-08 7.5 High
An issue in the ConfirmNameConstraints() function (wolfcrypt/src/asn.c) of wolfSSL v5.9.1 and v5.9.2 allows attackers to cause a Denial of Service (DoS) via providing crafted Certificate Authority certificates, leading to valid certificates without SAN to be incorrectly rejected by wolfSSL-based TLS clients.
CVE-2026-95184 2026-10-08 7.5 High
Improper certificate validation in gnutls v3.8.13 causes the application to reject legitimate certificates for valid users, leading to a Denial of Service (DoS).
CVE-2026-107318 2026-10-08 7.4 High
@fastify/reply-from is a Fastify plugin that forwards requests to an upstream HTTP or HTTPS server. In versions prior to 12.7.0, all of the built-in HTTPS transports override the secure default and set rejectUnauthorized to false, so the proxy does not verify the TLS certificate of the upstream even when the application points it at an https upstream in the default configuration. An on-path network attacker can therefore impersonate the configured HTTPS upstream, read the credentials and request bodies the proxy forwards, and return forged responses that the application trusts. The issue is fixed in @fastify/reply-from 12.7.0, and users should upgrade to 12.7.0 or later. As a workaround, pass an explicit rejectUnauthorized true on the transport, supply an already configured undici instance, or use the undici global agent.
CVE-2026-95210 2026-10-08 9.1 Critical
Improper certificate validation in gnutls v3.8.13 causes the application to accept certificates containing invalid extensions.
CVE-2026-87425 2026-10-08 N/A
An unauthenticated remote attacker can modify the TLS client trust store in Brocade ASCG versions before 3.5.0. By supplying an unauthorized Certificate Authority (CA) certificate to an unauthenticated management interface, the attacker can cause the system to trust unauthorized certificates, potentially enabling Man-in-the-Middle (MITM) attacks against outbound communications with managed switches and peer nodes.
CVE-2026-107587 2026-10-08 5.9 Medium
Improper certificate validation in the webmail of Progressive Robot hMailServer 6.3.2 through 6.3.5 allows a remote unauthenticated attacker to have S/MIME-encrypted mail that the account later sends to another correspondent also encrypted to the attacker's key. When its recipient opened a signed message, the webmail kept the signer's certificate for encrypting replies whether or not the server found its chain trusted, under the first e-mail address the certificate listed rather than the message's From address, and beside any certificate already held for that address. Encrypted mail later sent from the webmail to that address was encrypted to every certificate held for it, so a holder of the kept certificate's key who obtains a copy of such a message can read it.
CVE-2026-91812 3 Foxit, Foxitsoftware, Microsoft 5 Pdf Editor, Pdf Reader, Foxit Pdf Editor and 2 more 2026-10-08 7.9 High
A vulnerability in Foxit PDF Editor/Reader’s update mechanism allows man-in-the-middle attackers to bypass certificate validation and package integrity checks, potentially enabling arbitrary code execution with system privileges.
CVE-2026-92543 2 Docker, Moby 2 Docker Engine, Moby 2026-10-07 7.4 High
Docker Engine classifies a registry hostname as insecure using an any-match DNS check. loadInsecureRegistries() injects 127.0.0.0/8 and ::1/128 as insecure CIDRs by default. isCIDRMatch resolves all of the hostname's addresses and returns true if a single address is in the insecure CIDR list. Because the transport re-dials the hostname rather than the CIDR-matching address, a DNS answer set of one loopback IP plus a non-loopback attacker IP disables certificate verification and enables HTTP fallback for the registry connection.
CVE-2026-18173 2 Ibm, Redhat 3 Financial Transaction Manager, Financial Transaction Manager Ftmfor Redhat Openshift, Openshift 2026-10-07 3.7 Low
IBM Financial Transaction Manager (FTM) for RedHat OpenShift could allow a remote attacker to obtain sensitive information due to improper enforcement of mutual TLS authentication.
CVE-2026-63697 1 Dell 1 System Update 2026-10-07 7.6 High
Dell System Update, versions prior to 2.3.0.0, contains an Improper Certificate Validation vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to Remote execution.
CVE-2026-105221 1 Defunkt 1 Gist 2026-10-06 7.4 High
The gist RubyGem before 6.1.0 contains an improper certificate validation vulnerability that allows on-path attackers to intercept HTTPS traffic because http_connection in lib/gist.rb sets VERIFY_NONE. Attackers can present any certificate to read or modify GitHub API traffic, stealing OAuth tokens and login credentials to read and modify the victim's gists.
CVE-2026-105222 2 Alexpechkarev, Bestwebsoft 2 Google-maps, Google Maps 2026-10-06 7.4 High
The alexpechkarev/google-maps Laravel package through 12.16 disables TLS certificate verification by default because the bundled config sets ssl_verify_peer to FALSE, which is passed to CURLOPT_SSL_VERIFYPEER. On-path attackers can present any certificate to intercept Google Maps web-service requests, steal the API key from the query string, and tamper with responses.
CVE-2026-105223 1 Maclof 1 Kubernetes-client 2026-10-06 7.4 High
maclof kubernetes-client 0.17.0 before 0.32.0 disables TLS certificate verification in parseKubeconfig() and parseKubeconfigFile() when a kubeconfig lacks certificate-authority-data, ignoring insecure-skip-tls-verify. On-path attackers can impersonate the Kubernetes API server to capture Bearer tokens or Basic credentials and tamper with WebSocket or REST API traffic.
CVE-2026-86131 1 Watchguard 2 Fireware, Fireware Os 2026-10-06 9.8 Critical
A code injection vulnerability in WatchGuard Fireware OS's BOVPN Over TLS client configuration handling allows an attacker who controls the remote VPN server to execute arbitrary commands as root on the connecting Firebox.
CVE-2026-63577 1 Legion Of The Bouncy Castle Inc. 1 Bc-csharp 2026-10-06 N/A
Improper certificate validation in the directoryName name-constraint check (PkixNameConstraintValidator.WithinDNSubtree) in Legion of the Bouncy Castle Inc. bc-csharp before 2.7.0 allows an attacker who controls, or can have certificates issued by, a name-constrained intermediate CA to get certificates accepted by PKIX path validation whose subject distinguished name, or a directoryName subjectAltName, lies outside the CA's permitted subtrees, via a name that places other RDNs ahead of a copy of the permitted RDN sequence, because the check looks for the constraint's first RDN anywhere in the name and compares the remaining RDNs from that position, instead of requiring the constraint to be an initial prefix of the name as RFC 5280 sections 4.2.1.10 and 7.1 require.
CVE-2026-63576 1 Legion Of The Bouncy Castle Inc. 1 Bc-csharp 2026-10-06 N/A
Improper certificate validation in PkixNameConstraintValidator (ExtractHostFromURL) in Legion of the Bouncy Castle Inc. bc-csharp before 2.7.0 allows a name-constrained subordinate CA, or anyone able to obtain certificates with chosen subjectAltName URIs from such a CA, to bypass permitted or excluded uniformResourceIdentifier name constraints during certification path validation via a URI whose path, query, fragment or userinfo contains characters such as '@' or ':', because the host was extracted by string slicing without first isolating the RFC 3986 authority component, so the host compared against the constraints could differ from the URI's actual host.
CVE-2026-67270 2026-10-06 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-2026-81447 1 Dell 6 Dell Openmanage Server Administrator Managed Node For Rhel 8.10, Dell Openmanage Server Administrator Managed Node For Rhel 9.4, Dell Openmanage Server Administrator Managed Node For Sles 15 and 3 more 2026-10-06 6.8 Medium
Dell OpenManage Server Administrator, versions prior to 11.1.0.3, contains an Improper Certificate Validation vulnerability. An unauthenticated attacker with adjacent network access could potentially exploit this vulnerability, leading to Information disclosure and Information tampering.
CVE-2026-105794 2026-10-06 N/A
MsQuic is a cross-platform C implementation of the IETF QUIC protocol exposed to C, C++, C#, and Rust. Prior to 2.4.20, 2.5.11, and 2.6.1, MsQuic clients using the OpenSSL or QuicTLS TLS backend do not properly verify that a server certificate matches the intended target server hostname. An on-path attacker can therefore present a certificate that does not match the intended target hostname and spoof the server in a man-in-the-middle attack. The Schannel backend is not affected. This issue is fixed in versions 2.4.20, 2.5.11, and 2.6.1.
