Name of the Vulnerable Software and Affected Versions GNOME Web (aka Epiphany) versions prior to 40.4 GNOME Web (aka Epiphany) versions 41.x prior to 41.1

Description The issue is related to a lack of protection for the web page structure in the Epiphany web browser, specifically in the implementation of the ephy-about:overview script.
