Does this matter?
Lower severity and a low EPSS score (0.46%). Track it; it rarely justifies an emergency change on its own.
Description
A duplicate `SystemPrincipal` object could be created when parsing a non-system html document via `DOMParser::ParseFromSafeString`. This could have lead to bypassing web security checks. This vulnerability affects Firefox < 109.
