CVE-2026-24070 | Local Privilege Escalation via DYLIB Injection in Native Instruments Native Access

Exp

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.

Base score Version Severity Vector Exploitability Impact Score source
8.8 3.1 HIGH
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:L)
A normal user session is enough; they don’t have to be admin.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
