Wing FTP Server before 8.2.6 Stored XSS via nowpath in Legacy Activity Page

Published Nov 2, 2026 CVSS 4.0 · 5.1 Medium EPSS < 1% KEV · Not listed
Description
Wing FTP Server before 8.2.6 contains a stored cross-site scripting vulnerability that allows authenticated web-client users to inject script by sending a crafted nowpath parameter to webclient/makethumb.html. Attackers can break out of the directory CDATA section in admin_get_lastconn.html XML to forge a connection id, which executes in administrators' browsers when admin_connection_list.html auto-refreshes, enabling Lua console abuse.
