CVE-2026-45552 roxy-wi CVE debrief

CVE-2026-45552 is a critical vulnerability in Roxy-WI, a web interface for managing Haproxy, Nginx, Apache, and Keepalived servers. The vulnerability has a CVSS score of 9.9 and a severity of CRITICAL. It was published on 2026-06-10T15:16:36.303Z and modified on 2026-06-10T19:37:41.437Z. The vulnerability is caused by missing decorators in the install blueprint, which omit both role and group checks. This allows any logged-in user, including the default guest role 4, to install/reconfigure exporters, WAF, and GeoIP databases on every server in the Roxy-WI database, regardless of tenant ownership. The Ansible playbooks run with the per-server SSH credential stored in Roxy-WI, which the credentials' rightful owner (a different tenant) has provisioned with sudo rights for the management workflow.

Who should care

Administrators and users of Roxy-WI are advised to take immediate action to mitigate this vulnerability.

Technical summary

The vulnerability is caused by missing decorators in the install blueprint, specifically in the app/routes/install/routes.py file. The individual endpoints install_exporter, install_waf, install_geoip, check_geoip, get_exporter_version, and get_task_status are not wrapped in page_for_admin and do not call roxywi_common.is_user_has_access_to_its_group(server_ip) or check_is_server_in_group(server_ip). Only the GET index page (install_monitoring) gates on roxywi_auth.page_for_admin(level=2).

Defensive priority

High

Recommended defensive actions

  • Apply patches or updates as soon as they become available.
