CVE-2026-38587: n/a
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.
AI Analysis
Technical Summary
This vulnerability in ONLYOFFICE DocSpace allows users with minimal privileges to retrieve sensitive owner information through multiple REST API endpoints due to insufficient access control. The flaw exists in versions prior to 3.2.1. The lack of proper authorization checks enables exposure of data that should be limited to administrators.
Potential Impact
Authenticated low-privilege users can access sensitive owner identifiers and profile information, potentially leading to privacy violations or information disclosure within the affected environment. There is no indication of remote unauthenticated exploitation or broader system compromise from the available data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to ONLYOFFICE DocSpace to trusted users and monitor for unauthorized access attempts. Avoid granting unnecessary permissions to low-level users. Follow vendor updates closely for patches or official mitigations.
