CVESevRiskCVSSEPSSKEVPublishedDescription
CVE-2024-34447Hig0.497.50.00May 3, 2024An issue was discovered in the Bouncy Castle Crypto Package For Java before BC TLS Java 1.0.19 (ships with BC Java 1.78, BC Java (LTS) 2.73.6) and before BC FIPS TLS Java 1.0.19. When endpoint identification is enabled in the BCJSSE and an SSL socket is created without an explicit hostname (as happens with HttpsURLConnection), hostname verification could be performed against a DNS-resolved IP address in some situations, opening up a possibility of DNS poisoning.
CVE-2026-41603Hig0.487.40.00Apr 28, 2026Improper Validation of Certificate with Host Mismatch vulnerability in Apache Thrift. This issue affects Apache Thrift: before 0.23.0. Users are recommended to upgrade to version 0.23.0, which fixes the issue.
CVE-2026-26214Hig0.487.40.00Feb 12, 2026Galaxy FDS Android SDK (XiaoMi/galaxy-fds-sdk-android) version 3.0.8 and prior disable TLS hostname verification when HTTPS is enabled (the default configuration). In GalaxyFDSClientImpl.createHttpClient(), the SDK configures Apache HttpClient with SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER, which accepts any valid TLS certificate regardless of hostname mismatch. Because HTTPS is enabled by default in FDSClientConfiguration, all applications using the SDK with default settings are affected. This vulnerability allows a man-in-the-middle attacker to intercept and modify SDK communications to Xiaomi FDS cloud storage endpoints, potentially exposing authentication credentials, file contents, and API responses. The XiaoMi/galaxy-fds-sdk-android open source project has reached end-of-life status.
CVE-2024-37015Hig0.487.40.00Aug 13, 2024An issue was discovered in Ada Web Server 20.0. When configured to use SSL (which is not the default setting), the SSL/TLS used to establish connections to external services is done without proper hostname validation. This is exploitable by man-in-the-middle attackers.
CVE-2024-12925Hig0.477.30.00Sep 1, 2025Improper Validation of Certificate with Host Mismatch vulnerability in Akınsoft QR Menü allows HTTP Response Splitting.This issue affects QR Menü: from s1.05.05 before v1.05.12.
CVE-2025-3501Hig0.468.20.00Apr 29, 2025A flaw was found in Keycloak. By setting a verification policy to 'ALL', the trust store certificate verification is skipped, which is unintended.
CVE-2024-2462Med0.44—0.00Jun 11, 2024Allow attackers to intercept or falsify data exchanges between the client and the server
CVE-2026-43869Hig0.407.30.00May 5, 2026Improper Validation of Certificate with Host Mismatch vulnerability in Apache Thrift. This issue affects Apache Thrift: before 0.23.0. Users are recommended to upgrade to version 0.23.0, which fixes the issue.
CVE-2026-34477Med0.385.90.00Apr 10, 2026The fix for CVE-2025-68161 https://logging.apache.org/security.html#CVE-2025-68161 was incomplete: it addressed hostname verification only when enabled via the log4j2.sslVerifyHostName https://logging.apache.org/log4j/2.x/manual/systemproperties.html#log4j2.sslVerifyHostName system property, but not when configured through the verifyHostName https://logging.apache.org/log4j/2.x/manual/appenders/network.html#SslConfiguration-attr-verifyHostName attribute of the <Ssl> element. Although the verifyHostName configuration attribute was introduced in Log4j Core 2.12.0, it was silently ignored in all versions through 2.25.3, leaving TLS connections vulnerable to interception regardless of the configured value. A network-based attacker may be able to perform a man-in-the-middle attack when all of the following conditions are met: * An SMTP, Socket, or Syslog appender is in use. * TLS is configured via a nested <Ssl> element. * The attacker can present a certificate issued by a CA trusted by the appender's configured trust store, or by the default Java trust store if none is configured. This issue does not affect users of the HTTP appender, which uses a separate verifyHostname https://logging.apache.org/log4j/2.x/manual/appenders/network.html#HttpAppender-attr-verifyHostName attribute that was not subject to this bug and verifies host names by default. Users are advised to upgrade to Apache Log4j Core 2.25.4, which corrects this issue.
CVE-2026-22747Med0.376.80.00Apr 22, 2026Vulnerability in Spring Spring Security. SubjectX500PrincipalExtractor does not correctly handle certain malformed X.509 certificate CN values, which can lead to reading the wrong value for the username. In a carefully crafted certificate, this can lead to an attacker impersonating another user. This issue affects Spring Security: from 7.0.0 through 7.0.4.
CVE-2025-4295Med0.304.60.00Jul 22, 2025Improper Validation of Certificate with Host Mismatch vulnerability in HotelRunner B2B allows HTTP Response Splitting.This issue affects B2B: before 04.06.2025.
CVE-2014-35220.00—0.03Aug 19, 2014The Serf RA layer in Apache Subversion 1.4.0 through 1.7.x before 1.7.18 and 1.8.x before 1.8.10 does not properly handle wildcards in the Common Name (CN) or subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof servers via a crafted certificate.
