CVE-2026-55381

InvoiceShelf: IDOR in InvoiceShelf estimate-to-invoice conversion allows any company user to read and tamper with other companies' estimates

Published Oct 14, 2026 CVSS 3.1 · 7.1 High EPSS < 1% KEV · Not listed
Description
InvoiceShelf is an open-source web & mobile app that helps track expenses, payments and create professional invoices and estimates. Prior to version 2.4.0, POST /api/v1/estimates/{estimate}/convert-to-invoice in ConvertEstimateController authorizes only the caller's create-invoice ability and does not authorize access to the route-bound Estimate. Because route-model binding can resolve an estimate from any company, an authenticated user with create-invoice ability can copy another company's line items, prices, totals, taxes, notes, currency, and customer data into an invoice in the attacker's company. The victim company's configured conversion action reaches checkForEstimateConvertAction and can also change or delete the original estimate. This issue is fixed in version 2.4.0.
