A critical vulnerability in the WeekBox application's self-update mechanism allowed attackers to serve malicious binaries through man-in-the-middle attacks or repository compromise. The `app-updater.service.js` file downloaded and installed updates from GitHub Releases without enforcing cryptographic hash verification before proceeding with the update. The fix adds mandatory SHA-256 digest validation that halts the update process if a valid hash is not present in the release metadata.
