Arturia Software Center Privilege Escalation

Arturia Software Center on macOS installs plugin uninstall scripts with world-writable permissions (777) in root-owned directories, allowing local attackers to modify these scripts and achieve privilege escalation when the Privileged Helper executes them during plugin removal. This vulnerability affects any macOS user with the Arturia Software Center installed and requires local access and user interaction to exploit. No patch is currently available.

The Arturia Software Center on macOS contains insufficient code signature validation in its Privileged Helper component, allowing unauthenticated clients to connect and execute privileged actions without proper authorization. This vulnerability affects all versions of Arturia Software Center and enables local privilege escalation attacks where an unprivileged user can escalate to root or system-level privileges. While no CVSS score or EPSS data is publicly available, the authentication bypass nature and privilege escalation impact classify this as a high-severity issue; no KEV listing or public proof-of-concept has been confirmed at this time.
