Summary
The affected software is the firmware of the Kiloview E3 NDI encoder, which uses a hard-coded signing secret for its session authentication tokens. An attacker who obtains the publicly available firmware could forge administrative session tokens and gain unauthenticated access to privileged device functions.

Read the original description
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.
