CVE-2026-24281 1 Apache 1 Zookeeper 2026-04-17 5.9 Medium
Hostname verification in Apache ZooKeeper ZKTrustManager falls back to reverse DNS (PTR) when IP SAN validation fails, allowing attackers who control or spoof PTR records to impersonate ZooKeeper servers or clients with a valid certificate for the PTR name. It's important to note that attacker must present a certificate which is trusted by ZKTrustManager which makes the attack vector harder to exploit. Users are recommended to upgrade to version 3.8.6 or 3.9.5, which fixes this issue by introducing a new configuration option to disable reverse DNS lookup in client and quorum protocols.
CVE-2026-32281 2 Go Standard Library, Golang 2 Crypto/x509, Go 2026-04-17 7.5 High
Validating certificate chains which use policies is unexpectedly inefficient when certificates in the chain contain a very large number of policy mappings, possibly causing denial of service. This only affects validation of otherwise trusted certificate chains, issued by a root CA in the VerifyOptions.Roots CertPool, or in the system certificate pool.
CVE-2026-29140 1 Seppmail 2 Secure Email Gateway, Seppmail Secure Email Gateway 2026-04-16 5.3 Medium
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-2026-1531 1 Redhat 4 Satellite, Satellite Capsule, Satellite Maintenance and 1 more 2026-04-16 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-2022-27782 4 Debian, Haxx, Redhat and 1 more 4 Debian Linux, Curl, Enterprise Linux and 1 more 2026-04-16 7.5 High
libcurl would reuse a previously created connection even when a TLS or SSHrelated option had been changed that should have prohibited reuse.libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse if one of them matches the setup. However, several TLS andSSH settings were left out from the configuration match checks, making themmatch too easily.
CVE-2022-22576 6 Brocade, Debian, Haxx and 3 more 18 Fabric Operating System, Debian Linux, Curl and 15 more 2026-04-16 8.1 High
An improper authentication vulnerability exists in curl 7.33.0 to and including 7.82.0 which might allow reuse OAUTH2-authenticated connections without properly making sure that the connection was authenticated with the same credentials as set for this transfer. This affects SASL-enabled protocols: SMPTP(S), IMAP(S), POP3(S) and LDAP(S) (openldap only).
CVE-2026-2748 1 Seppmail 2 Seppmail, Seppmail Secure Email Gateway 2026-04-16 5.3 Medium
SEPPmail Secure Email Gateway before version 15.0.1 improperly validates S/MIME certificates issued for email addresses containing whitespaces, allowing signature spoofing.
CVE-2026-30840 2 Ellite, Wallosapp 2 Wallos, Wallos 2026-04-16 N/A
Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.6.2, there is a server-side request forgery vulnerability in notification testers. This issue has been patched in version 4.6.2.
CVE-2026-1530 1 Redhat 4 Satellite, Satellite Capsule, Satellite Maintenance and 1 more 2026-04-16 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-2026-24734 2 Apache, Apache Tomcat 3 Tomcat, Tomcat Native, Apache Tomcat 2026-04-16 7.4 High
Improper Input Validation vulnerability in Apache Tomcat Native, Apache Tomcat. When using an OCSP responder, Tomcat Native (and Tomcat's FFM port of the Tomcat Native code) did not complete verification or freshness checks on the OCSP response which could allow certificate revocation to be bypassed. This issue affects Apache Tomcat Native:  from 1.3.0 through 1.3.4, from 2.0.0 through 2.0.11; Apache Tomcat: from 11.0.0-M1 through 11.0.17, from 10.1.0-M7 through 10.1.51, from 9.0.83 through 9.0.114. The following versions were EOL at the time the CVE was created but are known to be affected: from 1.1.23 through 1.1.34, from 1.2.0 through 1.2.39. Older EOL versions are not affected. Apache Tomcat Native users are recommended to upgrade to versions 1.3.5 or later or 2.0.12 or later, which fix the issue. Apache Tomcat users are recommended to upgrade to versions 11.0.18 or later, 10.1.52 or later or 9.0.115 or later which fix the issue.
CVE-2026-30794 6 Apple, Google, Linux and 3 more 7 Iphone Os, Macos, Android and 4 more 2026-04-16 8.1 High
Improper Certificate Validation vulnerability in rustdesk-client RustDesk Client rustdesk-client on Windows, MacOS, Linux, iOS, Android (HTTP API client, TLS transport modules) allows Adversary in the Middle (AiTM). This vulnerability is associated with program files src/hbbs_http/http_client.Rs and program routines TLS retry with danger_accept_invalid_certs(true).

CVE-2026-3822 1 Taipower 1 Taipower App 2026-04-16 6.5 Medium
Taipower APP for Andorid developed by Taipower has an Improper Certificate Validation vulnerability. When establishing an HTTPS connection with the server, the application fails to verify the server-side TLS/SSL certificate. This flaw allows an unauthenticated remote attackers to exploit the vulnerability to perform a Man-in-the-Middle (MITM) attack to read and tamper with network packets.
CVE-2026-27221 3 Adobe, Apple, Microsoft 6 Acrobat, Acrobat Dc, Acrobat Reader and 3 more 2026-04-16 5.5 Medium
Acrobat Reader versions 24.001.30307, 24.001.30308, 25.001.21265 and earlier are affected by an Improper Certificate Validation vulnerability that could result in a Security feature bypass. An attacker could leverage this vulnerability to spoof the identity of a signer. Exploitation of this issue requires user interaction.
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-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-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

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.
