CVE-2026-116677 (GCVE-0-2026-116677)

Vulnerability from cvelistv5 – Published: 2026-10-27 17:23 – Updated: 2026-11-02 19:35

Title

OpenWISP Controller CA CRL REST API does not scope requests to managed organizations

Summary

OpenWISP Controller is a network and WiFi controller for provisioning, configuration management, updates, and PKI management. From 1.0.0 until 1.3.2, the GET /api/v1/controller/ca/<integer-id>/crl endpoint allows an authenticated organization manager with CA view permission to retrieve another organization's certificate revocation list by requesting its sequential CA identifier. CrlDownloadView.retrieve resolves the CA directly instead of using the organization-scoped object retrieval enforced by FilterByOrganizationManaged, bypassing the endpoint's intended authorization boundary. The response can disclose CA issuer information and revoked certificate serial numbers, but it does not expose CA private keys or allow modification. This issue is fixed in version 1.3.2.

Severity

Vulnerability from github – Published: 2026-10-30 22:58 – Updated: 2026-10-30 22:58

Summary

OpenWISP Controller CA CRL REST API does not scope requests to managed organizations

Details

Summary

The authenticated REST API endpoint for downloading a CA Certificate Revocation List resolves the requested CA without applying the organization-scoped queryset used by the rest of the PKI API.

An organization manager with CA view permission can request another organization's sequential CA ID and receive that CA's CRL. The endpoint is intended to be authenticated and organization-scoped, so it should use the same access-control path as GET /api/v1/controller/ca/<id>/.

Affected endpoint

GET /api/v1/controller/ca/<integer-id>/crl

CrlDownloadView inherits ProtectedAPIMixin, which requires an authenticated organization manager with the relevant model permission. However, retrieve() resolves the CA with get_object_or_404(Ca, pk=kwargs["pk"]). This bypasses FilterByOrganizationManaged and does not perform an object-level permission check.

Consequently, a manager of organization A can enumerate CA integer IDs and retrieve the CRL for a CA belonging to organization B. The sibling CA detail endpoint is correctly organization-scoped and returns 404 for the same cross-organization request.

Impact

The endpoint returns only the CRL, including CA issuer information and revoked certificate serial numbers. It does not disclose CA private keys and does not permit modification.

django-x509 exposes CRLs publicly by default unless DJANGO_X509_CRL_PROTECTED = True. Therefore, the default configuration does not gain a new confidentiality exposure from this REST API behavior. Nonetheless, the endpoint is part of the authenticated, organization-scoped REST API and does not enforce its intended authorization boundary.

Deployments that explicitly protect CRLs have a stronger expectation that this endpoint will scope access to the requester's managed organizations. The practical impact is low, but the authorization behavior should be corrected for consistency and defense in depth.

Remediation

Resolve the CA through the view's organization-scoped queryset. Set queryset = Ca.objects.all(), replace the direct get_object_or_404(Ca, pk=kwargs["pk"]) lookup with self.get_object(), and add a regression test that a same-organization manager receives 200 while a manager of another organization receives 404.

Severity

5.3 (Medium)
