Name of the Vulnerable Software and Affected Versions Firefox versions prior to 74

Description The issue arises when a JavaScript URL (javascript:) is evaluated and the result is a string. This string is then parsed to create an HTML document. Previously, the document's URL, as reported by properties like document.location, would incorrectly display the originating javascript: URL, potentially leading to spoofing attacks. This has been corrected to display the URL of the originating document instead.

Recommendations For versions prior to 74, update to version 74 or later to resolve the issue.
