CVE-2024-37889Public exploitNetwork attack vector

Cross-account invoice disclosure via unchecked invoice ID

Published Jun 14, 2024 · Updated Aug 2, 2024

Authorization bypass in TreyWW MyFinances before 0.4.6 allows remote authenticated users to read other customers' invoices. The invoice_edit_page_get view loads an Invoice from the user-controlled invoice_id and renders its data without calling the model's access check. Any signed-in account can replace the numeric invoice identifier in an edit-page request to disclose another customer's PII and financial data.
