Submit #821930: Dolibarr Dolibarr ERP/CRM <=23.0.1 Incorrect Authorizationinfo

TitleDolibarr Dolibarr ERP/CRM <=23.0.1 Incorrect Authorization
DescriptionDolibarr ERP/CRM 23.0.0 contains an improper authorization vulnerability in the Leave Request REST API. An authenticated low-privileged user with permission to read only their own and their subordinates' leave requests can access leave requests belonging to other users via the /api/index.php/holidays/{id} endpoint. The Web UI correctly enforces hierarchy-based authorization checks, but the REST API endpoint bypasses these checks due to inconsistent parameter handling in checkUserAccessToObject(), allowing horizontal privilege escalation and disclosure of sensitive business data.
