CVE-2026-113797: Electron: Extension tabs.query returns tab URLs and titles without the tabs permission
Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to versions 42.11.1, 43.5.1, 44.1.1, and 45.0.0-alpha.4, chrome.tabs.query() returned each tab's url and title to extensions that had neither the tabs permission nor matching host permissions. An application that loaded an extension it did not fully trust through session.extensions.loadExtension could therefore allow that extension to read the URL and title of every webContents in its session. This issue is fixed in versions 42.11.1, 43.5.1, 44.1.1, and 45.0.0-alpha.4.
