Apple · Cups · CVE-2018-4181
**Name of the Vulnerable Software and Affected Versions**
macOS High Sierra versions prior to 10.13.5
**Description**
The issue is related to the CUPS print server and involves improper handling of certain include directives, allowing an unprivileged user to read arbitrary files as a superuser. This enables an attacker to access confidential data. The problem was addressed by improving access restrictions.
**Recommendations**
For macOS High Sierra versions prior to 10.13.5, update to version 10.13.5 or later to resolve the issue. As a temporary workaround, consider restricting access to the CUPS service until the update is applied.
