CVE-2026-109559

EdgeEver Desktop 1.6.26 through 1.112.0 contains a navigation allowlist bypass that lets attackers load arbitrary origins in the main window via string-prefix URL matching. Attackers can embed a link using userinfo syntax after the dev-server prefix, for example in a note-template preview, to obtain the edgeeverDesktop bridge including session token, sidecar RPC, and ACP channels.
