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-2025-62375 1 Go-witness 1 Go-witness 2026-04-15 5.9 Medium
go-witness and witness are Go modules for generating attestations. In go-witness versions 0.8.6 and earlier and witness versions 0.9.2 and earlier the AWS attestor improperly verifies AWS EC2 instance identity documents. Verification can incorrectly succeed when a signature is not present or is empty, and when RSA signature verification fails. The attestor also embeds a single legacy global AWS public certificate and does not account for newer region specific certificates issued in 2024, making detection of forged documents difficult without additional trusted region data. An attacker able to supply or intercept instance identity document data (such as through Instance Metadata Service impersonation) can cause a forged identity document to be accepted, leading to incorrect trust decisions based on the attestation. This is fixed in go-witness 0.9.1 and witness 0.10.1. As a workaround, manually verify the included identity document, signature, and public key with standard tools (for example openssl) following AWS’s verification guidance, or disable use of the AWS attestor until upgraded.
CVE-2025-44018 1 Gl-inet 1 Gl-axt1800 2026-04-15 8.3 High
A firmware downgrade vulnerability exists in the OTA Update functionality of GL-Inet GL-AXT1800 4.7.0. A specially crafted .tar file can lead to a firmware downgrade. An attacker can perform a man-in-the-middle attack to trigger this vulnerability.
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-2025-15573 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-2022-32509 1 Nuki 3 Bridge V1, Bridge V2, Smart Lock 2026-04-15 8.8 High
