Permission bypass via unsigned library injection
Published Dec 18, 2024 · Updated Dec 20, 2024
Library injection in Microsoft OneNote 16.83 for macOS allows local users to exercise the application's granted permissions. The hardened application loads frameworks through relative paths while the com.apple.security.cs.disable-library-validation entitlement permits unsigned dynamic libraries. A local malicious application must copy and launch OneNote from a controllable location; injected code then inherits previously granted access, including audio, files, and Outlook automation.
