# Acronis Cyber Infrastructure: improper authorization exposes and alters sensitive data

Acronis Cyber Infrastructure builds before 6.0.1-112, 6.1.1-64 and 6.2.1-71 fail to check authorization properly on some operations. An attacker can read sensitive information and change data they should not reach.

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

## How to check

- Check the installed ACI build number against the fixed builds listed in the fix field
- unknown for other checks, the sources do not say which component or interface is involved

## Fix

- Upgrade Acronis Cyber Infrastructure to `6.0.1-112` or later on the 6.0 branch
- Upgrade Acronis Cyber Infrastructure to `6.1.1-64` or later on the 6.1 branch
- Upgrade Acronis Cyber Infrastructure to `6.2.1-71` or later on the 6.2 branch
