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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N","score":7.2},"cvss_v3":null,"cwes":["CWE-284","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-wxrv-73x6-8r62","https://github.com/InvoiceShelf/InvoiceShelf/security/advisories/GHSA-wxrv-73x6-8r62"],"products":[],"source":"nvd","synced_at":"2026-10-19T23:00:53.604569364+00:00"},"epss":{"cve":"CVE-2026-55387","score":0.00433,"percentile":0.37291,"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).
