CVE-2026-45566

Summary

Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions 8.2.6.4 and prior, the login flow allow-lists next URLs by rejecting strings containing https:// or http:// substrings, then constructs https://{request.host}{next_url} and the JS client redirects via window.location.replace(). The block does not consider the userinfo@host syntax. next=@evil.example/path produces https://victim.example@evil.example/path, which all modern browsers route to evil.example. At time of publication, there are no publicly available patches.
