Cross-account data disclosure via altered object IDs

Published Sep 7, 2022 · Updated Aug 3, 2024

Authorization bypass in WeDayCare B.V Ouderapp before 1.1.22 allows remote authenticated users to read other families' data. API request handlers accept child, parent, chat, and related object IDs without verifying that the requested record belongs to the authenticated account. A valid account and an intercepted API call are required; changing or brute-forcing identifiers exposes personal and chat records across families.
