3DescriptionCVE.org
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.
AnalysisAI
Improper authorization in Dolibarr's expense report REST API update endpoint allows authenticated users with only expense-creation rights to self-approve their own expense reports by directly manipulating workflow state fields, including approval status and approver identity. All Dolibarr versions before 24.0.0 are affected; a publicly available proof-of-concept exploit demonstrates the bypass. …
