CVE-2021-39203
In affected versions authenticated users who don't have permission to view private post types/data can bypass restrictions in the block editor under certain conditions.
Does this matter?
Lower severity and a low EPSS score (0.94%). Track it; it rarely justifies an emergency change on its own.
