CVE-2025-61781
Published: 05 January 2026
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.
Mitigating Controls (NIST 800-53 r5)AI
Enforces approved authorizations for logical access to information and system resources, directly addressing the missing ownership verification in the WorkspacePopoverDeletionMutation.
Provides capability to make access control decisions based on ownership attributes, mitigating bypass through supply of unauthorized UUIDs.
Employs least privilege to restrict low-privilege users from deleting workspaces they do not own, complementing proper authorization enforcement.
Security SummaryAI
CVE-2025-61781 affects OpenCTI, an open source platform for managing cyber threat intelligence knowledge and observables, in versions prior to 6.8.1. The vulnerability resides in the GraphQL mutation "WorkspacePopoverDeletionMutation," which enables deletion of workspace-related objects such as dashboards and investigation cases. This mutation lacks proper authorization checks to verify the requester's ownership of the targeted resources, allowing unauthorized actions based on CWE-285 (Improper Authorization), CWE-566 (Authorization Bypass Through User-Controlled Key), CWE-915 (Improperly Controlled Modification of Dynamically-Determined Object Attributes), and CWE-863 (Incorrect Authorization). The issue carries a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:H), indicating high availability impact with low integrity impact.
An authenticated attacker with low privileges (PR:L) can exploit this vulnerability over the network with low complexity and no user interaction required. By supplying the active UUID of a workspace owned by another user, the attacker bypasses ownership validation, causing the mutation to execute successfully and resulting in the complete unauthorized deletion of the targeted workspace.
The GitHub Security Advisory at https://github.com/OpenCTI-Platform/opencti/security/advisories/GHSA-pr6m-q4g7-342c details the issue and confirms that upgrading to OpenCTI version 6.8.1 resolves the vulnerability by implementing the necessary authorization checks.

MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
The vulnerability enables unauthorized deletion of workspaces and related objects (dashboards, investigation cases) in OpenCTI via authorization bypass in GraphQL mutation, causing high availability impact (CVSS A:H) consistent with application exploitation for DoS (T1499.004) and data destruction (T1485).
