CVE-2026-71509Network attack vectorHinoki check available

Expense approval bypass via unrestricted field updates

Published Aug 24, 2026 · Updated Aug 24, 2026

Improper authorization in Dolibarr ERP & CRM before 24.0.0 allows remote authenticated users to approve expense reports via its REST API. The update endpoint mass-assigns attacker-controlled status, approver, and approval-state fields without checking the dedicated approval right or generating the normal approval timestamp. Expense-creation rights are sufficient to move reports to approved or closed states, corrupting workflow integrity and leaving inconsistent audit records.
