CVE-2026-92450
Kiloview E3 NDI Encoder Use of Hard-coded Credentials
What happened?
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.
Affected software and versions

This CVE was not listed in the CISA catalogue at our last retrieval. This does not establish that exploitation is absent.
How to respond
- Confirm the product, installed package version, and any configuration requirements in the vendor advisory.
- Follow the vendor’s remediation or workaround guidance in the references below. Structured fixed-version data is unavailable here; the publisher’s description may include a fix or workaround.
- Restart affected services if required, then verify the running version. Known exploitation may warrant investigation as well as patching.
