A note from upstream, in case it's helpful: we haven't depended on cmark-gfm since pandoc 2.10.1 (released a year and a half ago). If you could move to a more recent version of pandoc, this would avoid the problem entirely. I'm aware that issues of policy and packaging may make this difficult, though.
