CVE-2026-24062 Arturia CVE debrief

A local privilege escalation vulnerability exists in the Arturia Software Center for macOS. The Privileged Helper component fails to adequately validate client code signatures when accepting connections, allowing an attacker to connect to the helper and execute privileged actions. This weakness enables a local attacker with low privileges to escalate to higher privileges without user interaction. The vulnerability is classified as CWE-306 (Missing Authentication for Critical Function). The CVE was published on March 18, 2026, and last modified on May 19, 2026. The NVD entry currently shows a status of 'Deferred'.

Who should care

Organizations and individuals using Arturia Software Center on macOS, particularly in multi-user environments or where untrusted local users may have access to systems with Arturia software installed.

Technical summary

The Arturia Software Center for macOS implements a Privileged Helper tool that performs insufficient validation of client code signatures when accepting connections. This authentication bypass allows any local process to connect to the helper and execute actions with elevated privileges. The vulnerability requires local access and low privileges but needs no user interaction, resulting in high impact to confidentiality, integrity, and availability of the affected system.

Defensive priority

HIGH

Recommended defensive actions

  • Update Arturia Software Center to the latest version as patches become available from the vendor
  • Audit macOS systems for installations of Arturia Software Center and prioritize patching on multi-user or shared systems
  • Monitor for unexpected privileged helper tool connections or XPC service anomalies related to Arturia components
  • Apply principle of least privilege by restricting software installation rights on macOS endpoints where Arturia products are deployed
  • Review system logs for unauthorized privilege escalation attempts involving Arturia helper tools

Evidence notes

The CVE description and NVD metadata confirm insufficient code signature validation in the Privileged Helper component. CVSS 3.1 vector: AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H.
