An issue was discovered in GUPnP before 1.0.7 and 1.1.x and 1.2.x before
1.2.5. It allows DNS rebinding. A remote web server can exploit this
vulnerability to trick a victim’s browser into triggering actions against
local UPnP services implemented using this library. Depending on the
affected service, this could be used for data exfiltration, data tempering,
etc.
