## Technical details

An Insecure Direct Object Reference (IDOR) vulnerability exists in Dolibarr ERP CRM versions 23.0.0 through 23.0.2 within the `htdocs/user/messaging.php` file. The application fails to properly validate if the requesting user has the necessary permissions to access a specific record identified by the 'ID' parameter. A remote, authenticated attacker can exploit this by manipulating the ID argument to bypass authorization checks and view data belonging to other users. The issue is rooted in an improper implementation of the `restrictedArea` check and has been addressed in version 23.0.3 by adding explicit ownership and permission validation.
