CVE-2023-27945

System log disclosure via improper entitlements

Published May 8, 2023 · Updated Jan 29, 2025

Information disclosure in Apple Xcode and macOS allows local users running a sandboxed app to collect system logs. Apple attributes the flaw to Dev Tools entitlements but has not disclosed the affected service, API, or entitlement check that exposes log data. Execution of an attacker-controlled sandboxed app and user interaction are required; the reported consequence is read access to system logs.
