112-112: 🔒 Security & Privacy | 🟠 Major | ⚡ Quick winRequire Unix owner identity in both predicates.
If another user can write to the temporary parent, they can replace the newly created directory before
InspectDirectoryreopens it. The Unix directory predicate then accepts an attacker-owned0700directory because it checks onlyUnixMode, allowing the attacker to modify the staging tree.
