CVE-2006-6506
The "Feed Preview" feature in Mozilla Firefox 2.0 before 2.0.0.1 sends the URL of the feed when requesting favicon.ico icons, which results in a privacy leak that might allow feed viewing services to determine browsing habits.
Does this matter?
Lower severity and a low EPSS score (1.81%). Track it; it rarely justifies an emergency change on its own.
