CVE-2026-121003
Description
A flaw was found in Epiphany. An information disclosure vulnerability allows local users to discover websites visited during private browsing sessions. When a user selects the "Always Allow" option for external URL schemes while in incognito mode, Epiphany stores the visited domain into the user's global configuration. Consequently, browsing history intended to be temporary is saved locally and can be read by local users or applications with access to user configuration settings.
