4thline cling uPnP protocol issue can lead to denial of service
An issue in the UPnP protocol in 4thline cling 2.0.0 through 2.1.2 allows remote attackers to cause a denial of service via an unchecked `CALLBACK` parameter in the request header. As of 2022, 4thline cling is no longer supported by the maintainers.
