# VitaFit Android app: unencrypted session tokens in backups enable account takeover

The VitaFit Android app (com.vt.vitafit) before 2.8.1.0 stores session tokens (m_session_id) unencrypted in application backups, and those tokens remain valid for ten years. An attacker who extracts a backup can reuse the token to read or modify the victim's account or delete its login record, locking the owner out.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed VitaFit version under the app's info screen or the Android package version for com.vt.vitafit; anything below `2.8.1.0` is in scope

## Fix

- VitaFit Android app: move to `2.8.1.0` or later

## From the sources

VitaFit Android application (com.vt.vitafit) before 2.8.1.0 contains an insecure session management vulnerability that allows attackers to extract or intercept unencrypted m_session_id tokens stored in application backups, which remain valid for ten years. Attackers can use a stolen session token to read and modify the victim's account or delete the account's authentication record, preventing the legitimate owner from logging in again.
