Quick assessment

Affected

Exploitation

Recommended action

在 Dolibarr 24.0.0 版本之前，费用报销 REST API 的更新端点存在权限验证不当的安全漏洞。该漏洞允许拥有费用创建权限的已认证攻击者，通过直接设置审批状态和审批人身份字段，绕过正常的审批工作流。攻击者可以利用 REST API 篡改工作流状态字段，将费用报销单推进至“已批准”或“已关闭”状态，而无需具备专门的审批权限。此外，由于缺少审批时间戳，还会在审计记录中造成取证不一致的问题。

Vulnerability Title
Dolibarr < 24.0.0 Expense Report REST API Improper Authorization via Update Endpoint
Source: CVE Program / CVE List V5
Vulnerability 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.
