CVE-2023-27967

App sandbox escape and elevated code execution

Published May 8, 2023 · Updated Jan 29, 2025

Memory-handling flaw in Apple Xcode before 14.3 allows local users to execute arbitrary code outside an app sandbox or with elevated privileges. Apple identifies the affected component only as Dev Tools and has not disclosed the faulty operation or the input that reaches it. Exploitation requires local execution and user interaction, and successful abuse escapes an app sandbox or gains elevated privileges.
