{"cve":"CVE-2026-55381","nvd":{"published":"2026-10-14T20:17:48.057","modified":"2026-10-15T21:08:49.703","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N","score":7.1},"cwes":["CWE-639"],"references":["https://github.com/InvoiceShelf/InvoiceShelf/commit/e432e4e62f5aa52238e3ff3fc37a0c78588eec47","https://github.com/InvoiceShelf/InvoiceShelf/pull/661","https://github.com/InvoiceShelf/InvoiceShelf/releases/tag/2.4.0","https://github.com/InvoiceShelf/InvoiceShelf/security/advisories/GHSA-j2vg-rxqr-5vc9","https://github.com/InvoiceShelf/InvoiceShelf/security/advisories/GHSA-j2vg-rxqr-5vc9"],"products":[],"source":"nvd","synced_at":"2026-10-19T23:00:53.604569364+00:00"},"epss":{"cve":"CVE-2026-55381","score":0.00364,"percentile":0.30012,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
