Researchers identified a vulnerability in macOS allowing the silent replacement of trusted app executables without elevated privileges or security warnings. Although Apple reviewed the issue, they determined it did not require a security fix, leaving users potentially exposed to impersonation attacks for accessing sensitive data like Keychain secrets.
Background
macOS employs strict code signing and notarization processes to ensure application integrity and user safety. This incident highlights potential gaps in how the operating system handles file modifications within bundled application directories during runtime.
