# Fuint: members can read other members' booking records by ID

Fuint, a membership and booking system, lets any logged-in member fetch another member's booking by changing the bookId value in the myBookDetail API. An attacker can iterate sequential IDs to collect names, mobile numbers, in-store verification codes and service details.

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

## How to check

- Confirm whether the deployment runs Fuint at or before commit `57ec018`, for example by checking the deployed repository revision.
- Test whether `/clientApi/book/myBookDetail` returns a booking that belongs to a different account when given another member's bookId (only on a test instance you control).

## Fix

- unknown

## From the sources

Fuint through commit 57ec018 contains an insecure direct object reference vulnerability that allows authenticated members to read other members' booking records by supplying arbitrary bookId values to /clientApi/book/myBookDetail. Attackers can iterate the auto-increment bookId to retrieve contact names, mobile numbers, in-store verification codes, service dates, stores and remarks.
