Summary

CVE-2026-24062 is a high-severity Missing Authentication for Critical Function (CWE-306) vulnerability in Sec Consult (inferred from references). Its CVSS base score is 7.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 3.4th 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-3 (Access Enforcement) and SA-19 (Component Authenticity).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploitation for Privilege Escalation (T1068). What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SA-19 Component Authenticity good match

prevent

Requires verification of client component authenticity prior to establishing a connection with the privileged helper, directly mitigating the insufficient code signature validation vulnerability.

AC-3 Access Enforcement good match

prevent

Enforces approved authorizations for access to the privileged helper, preventing unauthorized clients from executing privileged actions leading to escalation.

AC-6 Least Privilege partial match

prevent

Limits privileges of the helper component to the minimum necessary, reducing the impact of local privilege escalation even if validation is bypassed.

Why these techniques?

Direct local privilege escalation via missing client authentication on a privileged helper tool (CWE-306).

Confidence: HIGH · MITRE ATT&CK Enterprise v18.1

NVD Description

The "Privileged Helper" component of the Arturia Software Center (MacOS) does not perform sufficient client code signature validation when a client connects. This leads to an attacker being able to connect to the helper and execute privileged actions leading to…

local privilege escalation.

Deeper analysisAI

CVE-2026-24062 is a vulnerability in the "Privileged Helper" component of the Arturia Software Center on macOS. The issue arises from insufficient client code signature validation when a client connects to the helper, enabling an attacker to perform privileged actions that lead to local privilege escalation. Published on 2026-03-18, it is associated with CWE-306 (Missing Authentication for Critical Function) and carries a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), reflecting high impact on confidentiality, integrity, and availability.

A local attacker with low privileges (PR:L) can exploit this vulnerability given its low attack complexity (AC:L) and lack of required user interaction (UI:N). By connecting to the privileged helper without adequate signature checks, the attacker gains the ability to execute arbitrary privileged actions, achieving full local privilege escalation from a standard user context.
