## Technical details

A vulnerability classified as CWE-494 (Download of Code Without Integrity Check) exists in Shirt Pocket SuperDuper! versions 3.10 and earlier. The software's auto-update mechanism fails to verify the signature and notarization of downloaded installer packages before execution. Because the macOS package installer runs with escalated privileges, a local attacker or malicious process can intercept the update request and substitute a malicious package. An exploit requires a legitimate update to be available and the user to trigger the 'Upgrade' process. The issue is resolved in version 3.11, which implements manual signature and notarization validation before installation.
