AnalysisAIv1 – Mar 12, 2026

Native Access on macOS allows local authenticated attackers to inject malicious libraries into the privileged XPC helper process due to overly permissive code signing entitlements, enabling arbitrary code execution with system-level privileges. The vulnerability stems from the application being signed with dyld environment variable and library validation bypass entitlements while communicating with a trusted helper that validates only the signing certificate. Public exploit code exists, and no patch is currently available.

Classified as CWE-426 (Untrusted Search Path). Affects Native Access. During the installation of the Native Access application, a privileged helper com.native-instruments.NativeAccess.Helper2, which is used by Native Access to trigger functions via XPC communication like copy-file, remove or set-permissions, is deployed as well. The communication with the XPC service of the privileged helper is only allowed if the client process is signed with the corresponding certificate and fulfills the following code signing requirement: "anchor trusted and certificate leaf[

HIGH 8.8

DescriptionCVE.org

During the installation of the Native Access application, a privileged helper com.native-instruments.NativeAccess.Helper2, which is used by Native Access to trigger functions via XPC communication like copy-file, remove or set-permissions, is deployed as well. The communication with the XPC service of the privileged helper is only allowed if the client process is signed with the corresponding certificate and fulfills the following code signing requirement: "anchor trusted and certificate leaf[subject.CN] = \"Developer ID Application: Native Instruments GmbH (83K5EG6Z9V)\""

The Native Access application was found to be signed with the com.apple.security.cs.allow-dyld-environment-variables and com.apple.security.cs.disable-library-validation entitlements leading to DYLIB injection and therefore command execution in the context of this application. A low privileged user can exploit the DYLIB injection to trigger functions of the privileged helper XPC service resulting in privilege escalation by first deleting the /etc/sudoers file and then copying a malicious version of that file to /etc/sudoers.

Executive ViewAI

Why It Matters

Native Access installations contain a privileged helper component vulnerable to unauthorized XPC-based command execution, potentially allowing attackers to execute arbitrary file operations with elevated privileges on affected systems. Organizations using Native Access for audio/music production software face risk of system compromise and data manipulation without immediate vendor patching.

Business Impact: High

Compensating Controls

Disable Native Access application if not business-critical; restrict XPC communication through macOS security policies (System Preferences > Security & Privacy > Privacy); implement application whitelisting to prevent unauthorized process execution; enforce least-privilege user accounts and disable local admin rights for standard users; monitor system logs for com.native-instruments.NativeAccess.Helper2 activity; network-segment music production workstations; consider hardware or VM isolation for affected systems until patch deployment.

Privilege Escalation HIGH

Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.
