Summary

CVE-2026-1453 is a critical-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Cisa (inferred from references). Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 28.8th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 AC-14 (Permitted Actions Without Identification or Authentication) and AC-2 (Account Management).

Threat & Defense at a Glance

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

AC-14 Permitted Actions Without Identification or Authentication good match

prevent

AC-14 directly identifies, authorizes, and monitors critical actions like administrator account creation or deletion that are permitted without identification or authentication, mitigating the core missing authentication vulnerability.

AC-2 Account Management good match

prevent

AC-2 enforces management of accounts including creation and deletion only by authorized personnel, preventing unauthenticated attackers from gaining administrative control via unauthorized account modifications.

IA-2 Identification and Authentication (Organizational Users) good match

prevent

IA-2 requires unique identification and authentication for users accessing system functions, directly countering the lack of authentication for critical administrator account operations.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

Why these techniques?

Missing authentication in a network-accessible management function allows unauthenticated remote exploitation of a public-facing application to create/delete admin accounts and gain full control.

NVD Description

A missing authentication for critical function vulnerability in KiloView Encoder Series could allow an unauthenticated attacker to create or delete administrator accounts. This vulnerability can grant the attacker full administrative control over the product.

Deeper analysisAI

CVE-2026-1453 is a missing authentication for critical function vulnerability (CWE-306) in the KiloView Encoder Series. This flaw allows an unauthenticated attacker to create or delete administrator accounts, potentially granting full administrative control over the affected product. Published on 2026-01-29, it carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), classifying it as critical.

An unauthenticated attacker with network access can exploit this vulnerability due to low attack complexity and no user interaction or privileges required. Successful exploitation enables the creation or deletion of administrator accounts, resulting in high impacts to confidentiality, integrity, and availability, and providing the attacker with complete control over the device.
