NewCVE-2026-113797 (opens in a new tab)How to fix?
Upgrade electron to version 42.11.1, 43.5.1, 44.1.1, 45.0.0-alpha.4 or higher.
Overview
electron is a framework which lets you write cross-platform desktop applications using JavaScript, HTML and CSS.
Affected versions of this package are vulnerable to Missing Authorization in TabsQueryFunction::Run in shell/browser/extensions/api/tabs/tabs_api.cc, where the tabs.query API populates the privileged url and title tab properties unconditionally, regardless of whether the calling extension holds the tabs permission or has host access to the tab's origin. An extension without those permissions can call tabs.query to read the URL and title of any open tab, leaking information that should be gated behind the tabs permission or host access. The tabs.get and tabs.update APIs already enforced this check correctly; only tabs.query was missing the guard.
Note: Apps are only affected if they load extensions via session.extensions.loadExtension that they do not fully trust.
