CVE-2024-53846 1 Erlang 1 Otp 2026-04-15 5.5 Medium
OTP is a set of Erlang libraries, which consists of the Erlang runtime system, a number of ready-to-use components mainly written in Erlang, and a set of design principles for Erlang programs. A regression was introduced into the ssl application of OTP starting at OTP-25.3.2.8, OTP-26.2, and OTP-27.0, resulting in a server or client verifying the peer when incorrect extended key usage is presented (i.e., a server will verify a client if they have server auth ext key usage and vice versa).
CVE-2024-54147 2026-04-15 6.8 Medium
Altair is a GraphQL client for all platforms. Prior to version 8.0.5, Altair GraphQL Client's desktop app does not validate HTTPS certificates allowing a man-in-the-middle to intercept all requests. Any Altair users on untrusted networks (eg. public wifi, malicious DNS servers) may have all GraphQL request and response headers and bodies fully compromised including authorization tokens. The attack also allows obtaining full access to any signed-in Altair GraphQL Cloud account and replacing payment checkout pages with a malicious website. Version 8.0.5 fixes the issue.
CVE-2025-12047 1 Lenovo 1 Scanner Pro 2026-04-15 5.3 Medium
A vulnerability was reported in the Lenovo Scanner pro application during an internal security assessment that, under certain circumstances, could allow an attacker on the same logical network to disclose sensitive user files from the application.
CVE-2024-5445 2026-04-15 3.8 Low
Ecosystem Agent version 4 < 4.1.5.2597 and Ecosystem Agent version 5 < 5.1.4.2473 did not properly validate SSL/TLS certificates, which could allow a malicious actor to perform a Man-in-the-Middle and intercept traffic between the agent and N-able servers from a privileged network position.
CVE-2025-7395 1 Wolfssl 1 Wolfssl 2026-04-15 N/A
A certificate verification error in wolfSSL when building with the WOLFSSL_SYS_CA_CERTS and WOLFSSL_APPLE_NATIVE_CERT_VALIDATION options results in the wolfSSL client failing to properly verify the server certificate's domain name, allowing any certificate issued by a trusted CA to be accepted regardless of the hostname.
CVE-2025-7390 1 Softing 4 Edgeaggregator, Edgeconnector, Opc and 1 more 2026-04-15 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-2025-15573 2 Solax, Solax Power 5 Pocket Wifi 3, Pocket Wifi+4gm, Pocket Wifi+lan and 2 more 2026-04-15 9.4 Critical
The affected devices do not validate the server certificate when connecting to the SolaX Cloud MQTTS server hosted in the Alibaba Cloud (mqtt001.solaxcloud.com, TCP 8883). This allows attackers in a man-in-the-middle position to act as the legitimate MQTT server and issue arbitrary commands to devices.
CVE-2025-20215 1 Cisco 2 Webex, Webex Meetings 2026-04-15 5.4 Medium
A vulnerability in the meeting-join functionality of Cisco Webex Meetings could have allowed an unauthenticated, network-proximate attacker to complete a meeting-join process in place of an intended targeted user, provided the requisite conditions were satisfied. Cisco has addressed this vulnerability in the Cisco Webex Meetings service, and no customer action is needed. This vulnerability existed due to client certificate validation issues. Prior to this vulnerability being addressed, an attacker could have exploited this vulnerability by monitoring local wireless or adjacent networks for client-join requests and attempting to interrupt and complete the meeting-join flow as another user who was currently joining a meeting. To successfully exploit the vulnerability, an attacker would need the capability to position themselves in a local wireless or adjacent network, to monitor and intercept the targeted network traffic flows, and to satisfy timing requirements in order to interrupt the meeting-join flow and exploit the vulnerability. A successful exploit could have allowed the attacker to join the meeting as another user. However, the Cisco Product Security Incident Response Team (PSIRT) is not aware of any malicious use of the vulnerability that is described in this advisory.
CVE-2025-28169 2026-04-15 8.1 High
BYD QIN PLUS DM-i Dilink OS v3.0_13.1.7.2204050.1 to v3.0_13.1.7.2312290.1_0 was discovered to cend broadcasts to the manufacturer's cloud server unencrypted, allowing attackers to execute a man-in-the-middle attack.
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.
CVE-2025-5279 2026-04-15 7.5 High
When the Amazon Redshift Python Connector is configured with the BrowserAzureOAuth2CredentialsProvider plugin, the driver skips the SSL certificate validation step for the Identity Provider. An insecure connection could allow an actor to intercept the token exchange process and retrieve an access token. This issue has been addressed in driver version 2.1.7. Users should upgrade to address this issue and ensure any forked or derivative code is patched to incorporate the new fixes.
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.
CVE-2025-52919 2026-04-15 4.3 Medium
In Yealink RPS before 2025-05-26, the certificate upload function does not properly validate certificate content, potentially allowing invalid certificates to be uploaded.
CVE-2025-53869 1 Brother 1 Multiple Mfps 2026-04-15 3.7 Low
Multiple MFPs provided by Brother Industries, Ltd. does not properly validate server certificates, which may allow a man-in-the-middle attacker to replace the set of root certificates used by the product with a set of arbitrary certificates.
CVE-2025-35983 1 Gallagher 1 Controller 7000 2026-04-15 6.5 Medium
Improper Certificate Validation (CWE-295) in the Controller 7000 OneLink implementation could allow an unprivileged attacker to perform a limited denial of service or perform privileged overrides during the initial configuration of the Controller, there is no risk for Controllers once they are connected. This issue affects Controller 7000: 9.30 prior to vCR9.30.250624a (distributed in 9.30.1871 (MR1)).

CVE-2024-12797 1 Redhat 5 Discovery, Enterprise Linux, Logging and 2 more 2026-04-15 6.3 Medium
Issue summary: Clients using RFC7250 Raw Public Keys (RPKs) to authenticate a server may fail to notice that the server was not authenticated, because handshakes don't abort as expected when the SSL_VERIFY_PEER verification mode is set. Impact summary: TLS and DTLS connections using raw public keys may be vulnerable to man-in-middle attacks when server authentication failure is not detected by clients. RPKs are disabled by default in both TLS clients and TLS servers. The issue only arises when TLS clients explicitly enable RPK use by the server, and the server, likewise, enables sending of an RPK instead of an X.509 certificate chain. The affected clients are those that then rely on the handshake to fail when the server's RPK fails to match one of the expected public keys, by setting the verification mode to SSL_VERIFY_PEER. Clients that enable server-side raw public keys can still find out that raw public key verification failed by calling SSL_get_verify_result(), and those that do, and take appropriate action, are not affected. This issue was introduced in the initial implementation of RPK support in OpenSSL 3.2. The FIPS modules in 3.4, 3.3, 3.2, 3.1 and 3.0 are not affected by this issue.
