## Summary

VitaFit Android apps before version 2.8.1.0 expose long-lived session tokens in application backups, which an attacker with local access can extract or intercept without logging in or any action by the user. A stolen token, valid for ten years, lets the attacker read and modify the victim's account or delete its authentication record, locking the legitimate owner out.
