CVE-2026-96616 · Severity: medium · CVSS 6.5 · Published 2026-10-22

The Kiloview E3 NDI Encoder is a network video device used in broadcast and streaming environments. Its web management interface issues authentication tokens with expiration times far beyond normal session lengths, effectively creating permanent access credentials. An attacker who intercepts or obtains a token through device compromise gains long-term authenticated access to manage the encoder without needing to re-authenticate.

## How to fix

- Fixed in Firmware 1.30

## Technical details

The vulnerability is insufficient session expiration (CWE-613) in the web management interface's token generation logic. An unauthenticated network attacker with access to the E3's management interface can intercept or obtain a valid authentication token during normal login and reuse it indefinitely for authenticated operations. No additional authentication or user interaction is required once the token is obtained; a fix is available in firmware version 1.30 and later.

## Affected products

- Kiloview E3 NDI Encoder firmware <1.30
