CVE-2023-41902

Local privilege escalation via crafted package installation

Published Sep 20, 2023 · Updated Sep 25, 2024

Privilege escalation in CoreCode MacUpdater before 2.3.8 and 3.x before 3.1.2 allows local users to gain elevated access via crafted .pkg files. The flaw lies in the privileged helper's XPC path for direct package installation, but public sources do not identify the specific missing XPC check. A local account and an installed privileged helper are required; successful abuse elevates the attacker's privileges on the Mac.
