What is CVE-2021-45085?

An XSS vulnerability exists in the GNOME Web browser (Epiphany) prior to version 40.4 and in version 41.x prior to 41.1. This security issue can be triggered via an about: page, particularly through the 'ephy-about:overview' functionality. It becomes exploitable when a user visits a malicious page frequently enough for it to be added to the browser's Most Visited list, potentially allowing an attacker to run arbitrary scripts in the context of the user’s browser.
