CVE-2026-34780

Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. From versions 39.0.0-alpha.1 to before 39.8.0, 40.0.0-alpha.1 to before 40.7.0, and 41.0.0-alpha.1 to before 41.0.0-beta.8, apps that pass VideoFrame objects (from the WebCodecs API) across the contextBridge are vulnerable to a context isolation bypass. An attacker who can execute JavaScript in the main world (for example, via XSS) can use a bridged VideoFrame to gain access to the isolated world, including any Node.js APIs exposed to the preload script. Apps are only affected if a preload script returns, resolves, or passes a VideoFrame object to the main world via contextBridge.exposeInMainWorld(). Apps that do not bridge VideoFrame objects are not affected. This issue has been patched in versions 39.8.0, 40.7.0, and 41.0.0-beta.8.
