CVE-2021-24977
The Use Any Font | Custom Font Uploader WordPress plugin before 6.2.1 does not have any authorisation checks when assigning a font, allowing unauthenticated users to sent arbitrary CSS which will then be processed by the frontend for all users.
Does this matter?
Lower severity and a low EPSS score (1.49%). Track it; it rarely justifies an emergency change on its own.
