CVE-2025-46289

Protected-data disclosure via flawed AppSandbox file handling

Published Dec 12, 2025 · Updated Dec 12, 2025

Authorization bypass in AppSandbox in Apple macOS 14 before 14.8.3, 15 before 15.7.3, and 26 before 26.2 allows local users to read protected data. Apple identifies a file-handling logic error in AppSandbox but has not disclosed the affected file operation or validation failure. Execution of a local app and user interaction are required; the reported consequence is limited to protected-data disclosure.
