Kiloview E3 NDI encoder firmware signs session JWTs with an HMAC-SHA256 secret hardcoded as the same static string on every device. Anyone who can obtain the publicly distributed firmware can recover that secret and forge arbitrary session tokens, including administrative ones, with no credentials. Over the network this yields unauthenticated access to privileged device functions. Affected firmware builds are not listed.
What to do: Apply Kiloview's update for CVE-2026-92450; no fixed version or workaround is stated.

Description · NVD
The 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.
