CVE-2005-3170 1 Microsoft 1 Windows 2000 2026-04-16 5 Medium
The LDAP client on Microsoft Windows 2000 before Update Rollup 1 for SP4 accepts certificates using LDAP Secure Sockets Layer (LDAPS) even when the Certificate Authority (CA) is not trusted, which could allow attackers to trick users into believing that they are accessing a trusted site.
CVE-2003-1229 2 Oracle, Sun 3 Jre, Java Web Start, Jsse 2026-04-16 N/A
X509TrustManager in (1) Java Secure Socket Extension (JSSE) in SDK and JRE 1.4.0 through 1.4.0_01, (2) JSSE before 1.0.3, (3) Java Plug-in SDK and JRE 1.3.0 through 1.4.1, and (4) Java Web Start 1.0 through 1.2 incorrectly calls the isClientTrusted method when determining server trust, which results in improper validation of digital certificate and allows remote attackers to (1) falsely authenticate peers for SSL or (2) incorrectly validate signed JAR files.
CVE-2002-0862 2 Apple, Microsoft 10 Macos, Internet Explorer, Office and 7 more 2026-04-16 N/A
The (1) CertGetCertificateChain, (2) CertVerifyCertificateChainPolicy, and (3) WinVerifyTrust APIs within the CryptoAPI for Microsoft products including Microsoft Windows 98 through XP, Office for Mac, Internet Explorer for Mac, and Outlook Express for Mac, do not properly verify the Basic Constraints of intermediate CA-signed X.509 certificates, which allows remote attackers to spoof the certificates of trusted sites via a man-in-the-middle attack for SSL sessions, as originally reported for Internet Explorer and IIS.
CVE-2019-12098 4 Debian, Fedoraproject, Heimdal Project and 1 more 5 Debian Linux, Fedora, Heimdal and 2 more 2026-04-15 7.4 High
In the client side of Heimdal before 7.6.0, failure to verify anonymous PKINIT PA-PKINIT-KX key exchange permits a man-in-the-middle attack. This issue is in krb5_init_creds_step in lib/krb5/init_creds_pw.c.
CVE-2026-21228 1 Microsoft 1 Azure Local 2026-04-15 8.1 High
Improper certificate validation in Azure Local allows an unauthorized attacker to execute code over a network.
CVE-2026-35560 4 Amazon, Apple, Linux and 1 more 5 Amazon Athena Odbc Driver, Athena Odbc, Macos and 2 more 2026-04-15 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-2019-20461 1 Alecto 1 Ivm-100 Firmware 2026-04-15 9.8 Critical
An issue was discovered on Alecto IVM-100 2019-11-12 devices. The device uses a custom UDP protocol to start and control video and audio services. The protocol has been partially reverse engineered. Based upon the reverse engineering, no password or username is ever transferred over this protocol. Thus, one can set up the camera connection feed with only the encoded UID. It is possible to set up sessions with the camera over the Internet by using the encoded UID and the custom UDP protocol, because authentication happens at the client side.
CVE-2024-13956 1 Abb 3 Aspect Enterprise, Matrix Series, Nexus Series 2026-04-15 6.7 Medium
SSL Verification Bypass vulnerabilities exist in ASPECT if administrator credentials become compromisedThis issue affects ASPECT-Enterprise: through 3.*; NEXUS Series: through 3.*; MATRIX Series: through 3.*.
CVE-2025-0254 2026-04-15 5.9 Medium
HCL Digital Experience components Ring API and dxclient may be vulnerable to man-in-the-middle (MitM) attacks prior to 9.5 CF226. An attacker could intercept and potentially alter communication between two parties.
CVE-2025-10548 1 Clevercontrol 1 Clevercontrol 2026-04-15 6.5 Medium
The CleverControl employee monitoring software (v11.5.1041.6) fails to validate TLS server certificates during the installation process. The installer downloads and executes external components using curl.exe --insecure, enabling a man-in-the-middle attacker to deliver malicious files that are executed with SYSTEM privileges. This can lead to full remote code execution with administrative rights. No patch is available as the vendor has been unresponsive. It is assumed that previous versions are also affected, but this is not confirmed.
CVE-2025-40744 1 Siemens 1 Solid Edge Se2025 2026-04-15 7.5 High
A vulnerability has been identified in Solid Edge SE2025 (All versions < V225.0 Update 11). Affected applications do not properly validate client certificates to connect to License Service endpoint. This could allow an unauthenticated remote attacker to perform man in the middle attacks.
CVE-2025-69412 1 Kde 1 Messagelib 2026-04-15 3.4 Low
KDE messagelib before 25.11.90 ignores SSL errors for threatMatches:find in the Google Safe Browsing Lookup API (aka phishing API), which might allow spoofing of threat data. NOTE: this Lookup API is not contacted in the messagelib default configuration.
CVE-2025-1001 2026-04-15 5.7 Medium
Medixant RadiAnt DICOM Viewer is vulnerable due to failure of the update mechanism to verify the update server's certificate which could allow an attacker to alter network traffic and carry out a machine-in-the-middle attack (MITM). An attacker could modify the server's response and deliver a malicious update to the user.
CVE-2024-27440 2026-04-15 4.8 Medium
The Toyoko Inn official App for iOS versions prior to 1.13.0 and Toyoko Inn official App for Android versions prior 1.3.14 don't properly verify server certificates, which allows a man-in-the-middle attacker to spoof servers and obtain sensitive information via a crafted certificate.

A TLS vulnerability exists in the phone application used to manage a connected device. The phone application accepts self-signed certificates when establishing TLS communication which may result in man-in-the-middle attacks on untrusted networks. Captured communications may include user credentials and sensitive session tokens.
CVE-2024-47258 2026-04-15 8.1 High
2N Access Commander version 2.1 and prior is vulnerable in default settings to Man In The Middle attack due to not verifying certificates of 2N edge devices. 2N has currently released an updated version 3.3 of 2N Access Commander, with added Certificate Fingerprint Verification. Since version 2.2 of 2N Access Commander (released in February 2022) it is also possible to enforce TLS certificate validation.It is recommended that all customers update 2N Access Commander to the latest version and use one of two mentioned practices.
CVE-2025-2183 1 Palo Alto Networks 1 Globalprotect App 2026-04-15 N/A
An insufficient certificate validation issue in the Palo Alto Networks GlobalProtect™ app enables attackers to connect the GlobalProtect app to arbitrary servers. This can enable a local non-administrative operating system user or an attacker on the same subnet to install malicious root certificates on the endpoint and subsequently install malicious software signed by the malicious root certificates on that endpoint.
CVE-2024-37311 2026-04-15 8.2 High
Collabora Online is a collaborative online office suite based on LibreOffice. In affected versions of Collabora Online, https connections from coolwsd to other hosts may incompletely verify the remote host's certificate's against the full chain of trust. This vulnerability is fixed in Collabora Online 24.04.4.3, 23.05.14.1, and 22.05.23.1.
CVE-2025-37730 1 Elastic 1 Logstash 2026-04-15 6.5 Medium
Improper certificate validation in Logstash's TCP output could lead to a man-in-the-middle (MitM) attack in “client” mode, as hostname verification in TCP output was not being performed when the ssl_verification_mode => full was set.
