Protected-data disclosure via unsafe symlink following
Published Jun 11, 2026 · Updated Jun 11, 2026
Symlink following in StorageKit in Apple macOS before 15.4 allows local users to access protected user data through a malicious app. StorageKit follows attacker-controlled symbolic links when handling file paths, allowing a protected target to escape the intended access boundary. Exploitation requires a local app and user interaction, and the published consequence is limited to reading protected user data.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
