# DollarDollar: expense endpoint lets logged-in users change other users' balances

Link for people: https://infrastack.ai/live/CVE-2026-125365 (this .md is for agents)

DollarDollar through version 4.4 has a missing authorization check in its add_expense() function. An authenticated user can send foreign account_id and group_id values to /add_expense to change other users' account balances and add expenses to groups they do not belong to.

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

## Affected

- vendor:DollarDollar affected range not listed fixed no fixed version listed

## How to check

- Look for an `/add_expense` route or an `add_expense()` function in the DollarDollar code, and check whether it verifies that the account and group belong to the logged-in user.
- Check the installed DollarDollar version and compare it with `4.4`.

## Fix

- DollarDollar: unknown (the sources do not name a fixed version).

## From the sources

DollarDollar through 4.4 contains a missing authorization vulnerability in add_expense() that allows authenticated users to modify other users' account balances by supplying foreign account_id values. Attackers can submit sequential account_id, destination_account_id, and group_id values to /add_expense to tamper with balances and inject expenses into foreign groups with an arbitrary payer.
