Alert meAnalysisAIv1 – Mar 12, 2026
Native Access's privileged XPC helper uses PID-based code signature verification, which is vulnerable to PID reuse attacks allowing local attackers with low privileges to bypass security checks and gain elevated access. Public exploit code exists for this vulnerability, and no patch is currently available. An attacker can leverage this flaw to achieve arbitrary code execution with the privileges of the helper process.
Earlier versions of this analysis (1)
It was found that the XPC service offered by the privileged helper of Native Access uses the PID of the connecting client to verify its code signature. This is considered insecure and can be exploited by PID reuse attacks. [CVSS 7.8 HIGH]

Technical ContextAI · show details
Affects Native Access. It was found that the XPC service offered by the privileged helper of Native Access uses the PID of the connecting client to verify its code signature. This is considered insecure and can be exploited by PID reuse attacks. The connection handler function uses _xpc_connection_get_pid(arg2) as argument for the hasValidSignature function. This value can not be trusted since it is vulnerable to PID reuse attacks.

Executive ViewAI
Native Access users are exposed to a privilege escalation vulnerability that allows attackers to bypass security controls through PID reuse attacks, potentially gaining unauthorized access to sensitive systems and data. This risk is elevated because no patch is currently available and public exploits exist, creating an immediate window of exposure for any organization using this software.
Disable Native Access privileged helper if functionality is not required for operations; implement application whitelisting to prevent unauthorized process execution; use OS-level mandatory access controls (SELinux/AppArmor) to restrict XPC service access; monitor and alert on unexpected process spawning and PID reuse patterns; restrict Native Access to isolated network segments with limited lateral movement capability; require multi-factor authentication for systems that depend on Native Access functionality.
