CVE-2026-109559 Details
Description
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.
A navigation allowlist bypass vulnerability has been identified in EdgeEver Desktop versions 1.6.26 through 1.112.0. This vulnerability allows attackers to load arbitrary origins in the main window by exploiting string-prefix URL matching. The issue arises because the navigation guard uses an unparsed string comparison to evaluate URLs, enabling the injection of links that bypass the intended restrictions. Attackers can exploit this vulnerability by embedding a crafted URL, using the userinfo syntax after the dev-server prefix, into a note-template preview. This manipulation grants access to the edgeeverDesktop bridge, including the session token, sidecar RPC, and ACP channels.
Users can update to EdgeEver Desktop version 1.113.0 or later, where this vulnerability has been fixed.
