What is CVE-2026-45552?
CVE-2026-45552 is a critical missing authorization vulnerability in roxy-wi, published on 10 Jun 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions 8.2.6.4 and prior, the install blueprint declares only bp.before_request → @jwt_required() (app/routes/install/routes.py:36-39). 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). Because the missing decorators omit both role and group checks, any logged-in user — including the default guest role 4 — can 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. At time of publication, there are no publicly available patches.
