An Insecure Direct Object Reference (IDOR) vulnerability was discovered in ONLYOFFICE DocSpace before 3.2.1. The flaw exists in multiple REST API endpoints. This allows authenticated users with low-level permissions (User or Guest) to retrieve sensitive information, such as the Owner's unique identifier (ID) and profile information, which should only be accessible to administrators.
