Local document enumeration via faulty permissions logic
Published Apr 2, 2021 · Updated Aug 3, 2024
Information disclosure in macOS before 11.0.1 allows local applications to enumerate a user's iCloud documents through the Sandbox. Apple identifies faulty permissions logic in Sandbox but does not disclose the affected code path or the precise incorrect operation. The required gate is execution of a local application with user interaction; the reported consequence is document enumeration, not content access or modification.
