CVE-2026-55387 Details
Description
InvoiceShelf is an open-source web & mobile app that helps track expenses, payments and create professional invoices and estimates. In version 2.3.3 and earlier, InvoiceShelf bulk-delete request validation accepts record identifiers without consistently binding them to the authenticated user's company_id. The affected DeleteCustomersRequest, DeleteEstimatesRequest, DeleteExpensesRequest, DeleteInvoiceRequest, DeleteItemsRequest, DeletePaymentsRequest, and DeleteUserRequest validators check that identifiers exist but do not consistently check tenant ownership. An authenticated user can submit another company's identifier and delete cross-company records. This vulnerability is fixed in 2.4.0.
A vulnerability in InvoiceShelf in versions prior to 2.4.0 allows authenticated users to delete records from other companies. The issue arises because the bulk-delete request validation does not consistently verify that record identifiers belong to the authenticated user's company. This flaw is present in several request validators, including those for deleting customers, estimates, expenses, invoices, items, payments, and users. As a result, an authenticated user can submit identifiers from another company and delete those cross-company records.
Users can upgrade to InvoiceShelf version 2.4.0, where this vulnerability has been fixed.
