CVE-2025-43465

Sensitive data access via directory path parsing

Published Dec 12, 2025 · Updated Dec 12, 2025

Path traversal in ATS in Apple macOS before 26.1 allows local users to access sensitive user data through a locally executed application. ATS parses directory paths without sufficient path validation, allowing an application-supplied path to reach data outside its intended location. Local application execution and low-privileged access are required, and the published impact is limited to disclosure of sensitive user data.
