CVE-2026-120491
Wing FTP Server before 8.2.6 Stored XSS via nowpath in Legacy Activity Page
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.
