The CSV **export** endpoint, `ExportSubnetView`, omits the organization-membership check that its **import** sibling performs, and loads the subnet by primary key with no organization filter. An authenticated user who is a member of one organization can therefore export a subnet belonging to **another** organization — its name, CIDR, organization slug and every IP address in it — by issuing an export request for that subnet's id.\n\n## Details\n\n`ImportSubnetView.post()` authorizes first, by calling `assert_organization_permissions()`:\n\n```python\n# openwisp_ipam/api/views.py  (ImportSubnetView)\ndef post(self, request, *args, **kwargs):\n    self.assert_organization_permissions(request)        # <-- org-membership check\n    file = request.FILES[\"csvfile\"]\n    ...\n    self.subnet_model().import_csv(file)\n```\n```python\n# openwisp_ipam/api/utils.py:16  (AuthorizeCSVImport)\ndef assert_organization_permissions(self, request):\n    if request.user.is_superuser:\n        return\n    # ... otherwise verifies the user belongs to the target organiza","public_affected_ranges":["<= 1.2.0.post1"]}],"null_published_at":"2026-11-04T10:04:27.942Z","source_updated_at":"2026-08-26T14:38:11.000Z","source_disclosed_at":"2026-08-26T14:38:10.000Z","is_synthetic_fixture":false,"null_last_reviewed_at":null,"public_change_summary":"First indexed by Null; source disclosure date is shown separately.","null_first_observed_at":"2026-11-02T09:56:37.775Z"}],"next_cursor":null,"snapshot_revision":"42594"}
