What is CVE-2026-110491?
The ONVIF service on the E3 can be rendered unresponsive by sending malformed or incomplete requests to certain operations. The affected service stops accepting new connections while the rest of the device continues operating normally, and will recover automatically after a period. This can be triggered repeatedly by any unauthenticated party with network access to the device.
CVSS Score Explained
CVSS 6.9 is Medium severity. Exploitation usually requires some specific conditions (local access, user interaction, or a particular config). Still worth patching in your next maintenance window.

Recent CVEs
- CVE-2026-92450The authentication framework used by affected Kiloview E3 NDI encoder firmware signs session JSON Web Tokens using an HMAC-SHA256 secret hardcoded as a static string within the firmware image, identical across all deployed devices. An attacker with access to the publicly distributed firmware can recover this secret and forge arbitrary session tokens, including administrative tokens, without valid credentials, enabling unauthenticated access to privileged device functions.8.7
- CVE-2026-110243The network management service on affected Kiloview E3 NDI encoder firmware fails to validate the network interface name accepted by its link maintenance address configuration endpoint before passing it to a shell command, unlike sibling handlers that perform the same validation. An authenticated web user with permission to configure network settings can exploit this to execute arbitrary operating system commands as root.9.4
- CVE-2026-110825The ONVIF device service on affected Kiloview E3 NDI encoder firmware accepts hostname, DNS, and NTP configuration write operations without requiring authentication, regardless of the device's configured authentication setting for this service. A remote, unauthenticated attacker can alter the device hostname, redirect DNS resolution, or modify the configured time source, enabling follow on attacks such as traffic interception or certificate validation bypass.8.7
- CVE-2026-107861The system control service on affected Kiloview E3 NDI encoder firmware fails to sanitize the hostname parameter accepted by its device naming endpoint, passing it unquoted into a shell command. An authenticated web user with access to this function can embed characters to execute arbitrary operating system commands as root, resulting in full device compromise.9.4
- CVE-2026-97785Improper authentication in AAD App Proxy allows an unauthorized attacker to elevate privileges over a network.10.0
- CVE-2026-96616Authentication tokens issued by the E3's web management interface on login are given an expiration time far beyond any reasonable session lifetime, effectively making them non-expiring. A token obtained through interception or device compromise remains valid for authenticated access for an extended period.8.3
