Vulnerability description
DayBreach CVE AI Research
CVE-2026-71509 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
Dolibarr before 24.0.0 contains an improper authorization vulnerability in the expense report REST API update endpoint that allows authenticated attackers with expense-creation rights to bypass the approval workflow by directly setting approval status and approver identity fields. Attackers can manipulate workflow state fields through the REST API to advance expense reports to approved or closed status without possessing the dedicated approval right, while also creating forensic inconsistencies in audit records due to missing approval timestamps.
