CVE-2025-61781
HighSummary
OpenCTI before version 6.8.1 contains a vulnerability in the GraphQL mutation WorkspacePopoverDeletionMutation that allows deletion of workspace-related objects (e.g., dashboards, investigation cases) without proper authorization. An attacker can supply another user's active UUID and delete the entire workspace because the API does not validate ownership.
Risk Assessment
The risk is that an attacker can unauthorizedly delete data, leading to loss of critical cyber threat intelligence and disruption of organizational operations.
Recommendation
Immediately upgrade OpenCTI to version 6.8.1 or later, which fixes the missing authorization. Additionally, restrict access to the GraphQL API to trusted users only.

In OpenCTI, versions 6.6.0 through 6.9.12, there is a privilege escalation vulnerability that can be exploited by unauthenticated attackers to query the API as any existing user, including the default admin account.
- CVE-2026-35211Medium
OpenCTI GraphQL API exposes a script filter operator in its FilterOperator enum that allows authenticated users with KNOWLEDGE capability to pass unsanitized Elasticsearch Painless scripts into search queries. This can cause CPU resource exhaustion and denial of service for all users.
- CVE-2026-35210High
In OpenCTI prior to version 7.260326.0, an authorization bypass vulnerability allows any authenticated user with KNOWLEDGE_KNUPDATE permission to bypass Confidence Level validation and Object Marking restrictions by injecting the synchronized-upsert: true HTTP header. This enables attackers to downgrade confidence levels, remove security markings like TLP:RED, manipulate relationships, and affect STIX object types including Indicators, ThreatActors, Malware, and Reports.
- CVE-2026-35212Medium
OpenCTI versions prior to 7.260227.0 are vulnerable to XSS in the rendering of email-message observable body data. The content of the body field isn't appropriately sanitized when being rendered. Requires user interaction but could be exploited by someone sharing STIX or any of the ingester.
- CVE-2026-44730High
OpenCTI is an open source platform for managing cyber threat intelligence knowledge and observables. Prior to 6.9.7, an organization admin can escalate their privileges by adding a user from a different organization with higher privileges to their own organization. This is due to incorrect ACL on userEdit relationAdd. This vulnerability is fixed in 6.9.7.
Original NVD description (English source)
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.
