... you seem to have missed the section 'Reporting a Bug' on page
https://freetype.org/developer.html
that you can reach if you follow the big, large 'Development' item in
the menu on the top-level page of 'freetype.org', then clicking on
'Bug Reports'. It would have told you to file an issue in our bug
tracker at
https://gitlab.freedesktop.org/groups/freetype/-/issues
which also supports confidential (i.e., non-public) reports.
Please do so the next time!
