Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
