Safari UXSS: ShareBear

Chains Safari and macOS flaws around iCloud ShareBear: after a user approves a benign shared file, its owner can replace it and relaunch it without another prompt. A mutated DMG plus Windows .url shortcut opens a quarantined webarchive in an attacker-chosen origin, yielding UXSS; related bugs allow sandbox escape and local-file access.
