Local-network access via improper permissions preservation
Published Mar 31, 2025 · Updated Apr 2, 2026
Permissions bypass in Apple Web Extensions allows local apps to gain unauthorized access to devices on the local network. The permission-checking path fails to preserve the platform's local-network access restrictions for an affected app or extension. Exploitation requires a locally running app and user interaction; Apple has not disclosed the specific check or the local-network requests exposed.
