CVE-2026-45565

Summary

Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions 8.2.6.4 and prior, EscapedString (app/modules/roxywi/class_models.py:16-30) is the centralised Pydantic validator used on dozens of fields including SSH credential name, username, description, etc. Its if/elif/elif/else flow returns the metacharacter-stripped value without also enforcing the .. block. An attacker who appends a single ;, &, |, $, or backtick to a .. payload routes the value through the strip arm, where .. survives unblocked and the result is not shlex.quote()'d either. At time of publication, there are no publicly available patches.
