CVE-2026-92450 · Severity: high · CVSS 7.5 · Published 2026-10-22

The Kiloview E3 NDI encoder is a video streaming device used for broadcast and professional AV applications. Its firmware signs session authentication tokens using a hardcoded secret key that is identical across all deployed devices and publicly available in firmware images. An attacker can extract this secret, forge administrative session tokens, and gain unauthorized access to device management functions without valid credentials.

## Quick answers

**Is CVE-2026-92450 exploited in the wild?** No. Junglewise Threat Intelligence has no report of CVE-2026-92450 being exploited in the wild.

**How severe is CVE-2026-92450?** High severity, with a CVSS score of 7.5, published 22 October 2026.

**Which products and versions are affected?** Kiloview E3 NDI Encoder <1.30.

**Is there a fix for CVE-2026-92450?** Yes: fixed in Firmware 1.30. Junglewise finds every place you run it, drafts the upgrade and applies it once you approve.

**How is CVE-2026-92450 attacked?** It is attacked over the network, in device firmware.

**Am I affected by CVE-2026-92450?** Check whether you run Kiloview E3 NDI Encoder at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## How to fix

- Fixed in Firmware 1.30

## Technical details

The authentication framework uses HMAC-SHA256 to sign JSON Web Tokens with a static, hardcoded secret embedded in the firmware image. Because the secret is identical across all devices and discoverable from publicly distributed firmware, an attacker can forge arbitrary session tokens including administrative ones. No authentication or network prerequisites are required beyond access to the firmware; successful exploitation grants unauthenticated access to privileged device functions.

## Affected products

- Kiloview E3 NDI Encoder <1.30
