CVE-2026-45549 roxy-wi CVE debrief

CVE-2026-45549 is a high-severity vulnerability in Roxy-WI, a web interface for managing Haproxy, Nginx, Apache, and Keepalived servers. The vulnerability affects versions 8.2.6.4 and prior. Specifically, the `agent_action` function in `app/routes/smon/agent_routes.py` (lines 166-179) lacks role checks and group ownership verification on the `server_ip` form field. Consequently, any authenticated user, including those with role 4 (guest), can initiate, halt, or restart the `roxy-wi-smon-agent` systemd unit on any server they specify. Since Roxy-WI executes systemd actions using its own SSH credentials with passwordless sudo, these actions run as root on the target server.
