NewCVE-2026-113796 (opens in a new tab)How to fix?
Upgrade electron to version 42.11.3, 43.7.0, 44.3.0, 45.0.0-alpha.6 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 Cross-site Request Forgery (CSRF) via the OpenURLFromTab handler, which fails to route modifier-click and middle-click link navigations (and target-form-post popups) through the window-open policy. A <webview> tag without allowpopups is supposed to block popup creation, but because these link-triggered navigations bypass the CanCreateWindow check that window.open() already passes through, an attacker-controlled page loaded in such a <webview> can open new windows that should have been blocked. Additionally, the new window starts its navigation from a fresh browser-initiated loadURL rather than from the original OpenURLParams, causing incorrect attribution of the initiator origin, Sec-Fetch-Site, SameSite cookies, and external protocol handling.
Note: This is only exploitable if the application loads untrusted content and allows it to open new windows.
