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-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.

CVE-2025-23091 2026-04-15 N/A
An Improper Certificate Validation on UniFi OS devices, with Identity Enterprise configured, could allow a malicious actor to execute a man-in-the-middle (MitM) attack during application update.
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-2025-23114 2026-04-15 N/A
A vulnerability in Veeam Updater component allows Man-in-the-Middle attackers to execute arbitrary code on the affected server. This issue occurs due to a failure to properly validate TLS certificate.
CVE-2025-10699 1 Lenovo 1 Lecloud 2026-04-15 5.3 Medium
A vulnerability was reported in the Lenovo LeCloud client application that, under certain conditions, could allow information disclosure.
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-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.
CVE-2024-31340 2026-04-15 4.8 Medium
TP-Link Tether versions prior to 4.5.13 and TP-Link Tapo versions prior to 3.3.6 do not properly validate certificates, which may allow a remote unauthenticated attacker to eavesdrop on an encrypted communication via a man-in-the-middle attack.

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-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-2025-15573 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-2025-2183 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-2025-22874 2026-04-15 7.5 High
Calling Verify with a VerifyOptions.KeyUsages that contains ExtKeyUsageAny unintentionally disabledpolicy validation. This only affected certificate chains which contain policy graphs, which are rather uncommon.
CVE-2025-30000 2026-04-15 6.7 Medium
A vulnerability has been identified in Siemens License Server (SLS) (All versions < V4.3). The affected application does not properly restrict permissions of the users. This could allow a lowly-privileged attacker to escalate their privileges.
CVE-2025-32057 1 Bosch 1 Infotainment System Ecu 2026-04-15 6.5 Medium
The Infotainment ECU manufactured by Bosch which is installed in Nissan Leaf ZE1 – 2020 uses a Redbend service for over-the-air provisioning and updates. HTTPS is used for communication with the back-end server. Due to usage of the default configuration for the underlying SSL engine, the server root certificate is not verified. As a result, an attacker may be able to impersonate a Redbend backend server using a self-signed certificate. First identified on Nissan Leaf ZE1 manufactured in 2020.
