CVE-2022-45403
Service Workers should not be able to infer information about opaque cross-origin responses; but timing information for cross-origin media combined with Range requests might have allowed them to determine the presence or length of a media file.
Does this matter?
Lower severity and a low EPSS score (0.70%). Track it; it rarely justifies an emergency change on its own.
