7.1 · HIGHOverview
CVE-2025-61781 is a high-severity vulnerability affecting citeum opencti. It was published on January 5, 2026 and has a CVSS 3.1 base score of 7.1 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.1, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.
Technical Description
OpenCTI is an open source platform for managing cyber threat intelligence knowledge and observables. Prior to version 6.8.1, the GraphQL mutation "WorkspacePopoverDeletionMutation" allows users to delete workspace-related objects such as dashboards and investigation cases. However, the mutation lacks proper authorization checks to verify ownership of the targeted resources.
An attacker can exploit this by supplying an active UUID of another user. Since the API does not validate whether the requester owns the resource, the mutation executes successfully, resulting in unauthorized deletion of the entire workspace. Version 6.8.1 fixes the issue.
Remediation
Check the references section for vendor advisories and patches from citeum. Update opencti to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
