I am afraid you confused projects. AFAIK the CVE is in the https://www.nuget.org/packages/Halibut/ which is a secure, RPC-based communication framework, but you opened bugs against https://www.chiark.greenend.org.uk/~sgtatham/halibut/, which is a documentation production system, with elements similar to TeX, debiandoc-sgml, TeXinfo, and others. It is primarily targeted at people producing software manuals. I.e. it seems there is nothing to fix at my side.
