What is CVE-2026-45561?

Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions 8.2.6.4 and prior, the /smon/agent/{version,uptime,status,checks}/<server_ip> family of routes takes the URL path component verbatim into requests.get(f'http://{server_ip}:{agent_port}/...'). The path component is constrained only by Flask's default URL converter, which permits any value (including IPv4 literals like 169.254.169.254, RFC1918 ranges, and 127.0.0.1). At time of publication, there are no publicly available patches.

Affected Version(s)
