CVE-2026-45565 roxy-wi CVE debrief

A vulnerability was discovered in Roxy-WI, a web interface used for managing Haproxy, Nginx, Apache, and Keepalived servers. The issue lies in the EscapedString validator, which is used on multiple fields, including SSH credential name, username, and description. This validator has a flawed if/elif/elif/else flow that fails to properly block the '..' character, allowing an attacker to bypass validation. By appending certain metacharacters such as ';', '&', '|', '$', or a backtick to a payload containing '..', an attacker can exploit this vulnerability. The affected versions are 8.2.6.4 and prior. At the time of publication, no patches are publicly available.
