Summary

CVE-2026-4272 is a high-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Https: (inferred from references). Its CVSS base score is 8.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 44th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-14 (Permitted Actions Without Identification or Authentication) and IA-2 (Identification and Authentication (Organizational Users)) — see the control section below for these in your framework.

CVE-2026-4272 is a Missing Authentication for Critical Function vulnerability in Honeywell Handheld Scanners, enabling Authentication Abuse. It affects specific versions of the scanner base stations: C1 Base (Ingenic x1000) prior to GK000432BAA, D1 Base (Ingenic x1600) prior to HE000085BAA, and A1/B1 Base (IMX25) prior to BK000763BAA, BK000765BAA, or CU000101BAA. The issue stems from a lack of authentication mechanisms for critical functions, as documented in the National Vulnerability Database (NVD) with a CVSS v3.1 base score of 8.1 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N) and mapped to CWE-306.

A remote attacker within Bluetooth range of the affected scanner's base station can exploit this vulnerability without authentication. Exploitation requires user interaction, allowing the attacker to remotely execute system commands on the host device connected to the base station. This grants high-impact confidentiality and integrity violations, potentially compromising the connected system.

Honeywell advisories, as referenced in the NVD entry (https://nvd.nist.gov/vuln/detail/CVE-2026-4272), strongly recommend upgrading to the latest firmware versions identified for each affected base station model to mitigate the vulnerability. No additional workaround details are provided in the available references.

Mitigating Controls (NIST 800-53 r5) AI

Directly mandates unique identification and authentication of users before access to functions requiring identity.

Extends the same authentication requirement to non-organizational users accessing critical functionality.

Requires authentication of services before they can invoke or expose critical functions.

Explicitly identifies and limits actions permitted without authentication, preventing critical functions from being exposed.

Access enforcement requires prior authentication before any authorization decision for critical functions.

PR.AA-03 full match
blocks

Directly requires authentication of users/services/hardware, which eliminates missing authentication for critical functions.

PR.AA-01 partial match
blocks

Managing identities and credentials is a prerequisite for authentication but does not itself enforce it on critical functions.

PR.AA-05 partial match
blocks

Defining and enforcing authorizations assumes prior authentication and therefore only partially mitigates the absence of authentication.

PR.IR-01 partial match
blocks

Protecting networks from unauthorized access can be undermined by missing authentication but does not address the root authentication gap.

blocks

A.8.5 mandates choosing and enforcing appropriate strong/multi-factor authentication techniques (with anti-brute-force, session, and log-on protections) that directly stop exploitation of missing auth on critical functions; the bounded remainder is non-interactive critical functions (e.g. unauthenticated APIs or resources) outside its user/entity authentication focus.
