AI-Generated

Flowintel versions prior to 3.3.0 are vulnerable to an insecure direct object reference issue that allows authenticated users with editor-level access to manipulate tasks across different cases. This flaw could lead to unauthorized access and modification of sensitive task data, posing a significant risk to data integrity and confidentiality. Organizations using affected versions should prioritize applying the patch to mitigate potential exploitation of this vulnerability.

Original NVD Description

Affected versions of Flowintel contain an insecure direct object reference / broken object-level authorization issue across numerous task endpoints. The routes generally received both a case identifier and a task identifier, but previously they did not enforce that the task actually belonged to the supplied case. As a result, an authenticated user with editor-level access to one case could potentially substitute the ID of a task from another case and invoke operations against that foreign task. The patch introduces task_case_bound_required, which loads both objects and returns 404 unless the task belongs to the requested case. This protection is applied to edit, delete, note, assignment, status, file, export, MISP-linking, subtask, external-reference, and other task-related endpoints. The fix also adds explicit checks that a requested note_id belongs to the current task before returning or exporting it, closing related cross-object access paths. Version impacted =>3.3.0
