CVE-2026-45560 roxy-wi CVE debrief

CVE-2026-45560 is a medium-severity XSS vulnerability in Roxy-WI, a web interface for managing servers. The vulnerability exists in versions 8.2.6.4 and prior, where the `wrap_line` and `highlight_word` functions in `app/modules/common/common.py` build raw HTML by string concatenation with no escaping. This allows an attacker to inject an SVG payload into HAProxy/Nginx access logs, which can be executed when a Roxy-WI admin opens the log viewer.
