The General HTML Support feature did not exist before v29, so versions lower than that are unaffected.

Hi @mhassan1, https://github.com/ckeditor/ckeditor5/releases/tag/v29.0.0 discusses the introduction of the General HTML Support feature, so I'm going to add that link to the references as a reminder of why a lower bound of >= 29.0.0 was added to the CVE record and the global GHSA.
