CVE-2026-70608

Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 39.8.10, 41.10.3, and 42.0.1, a sandboxed iframe without the allow-popups keyword could still open a new window or trigger setWindowOpenHandler with no user interaction because...

Improper Neutralization of Special Elements Used in a Template Engine

Overview Affected versions of this package are vulnerable to Improper Neutralization of Special Elements Used in a Template Engine in the getTwigValue process. An attacker can execute arbitrary code by injecting malicious Twig templates into content fields that are rendered without sandboxing. Th...

Incorrect Permission Assignment for Critical Resource

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 Incorrect Permission Assignment for Critical Resource via the openExternal. An attacker can cause an OS-registered external...

Electron: Sandboxed iframes can launch external protocol handlers

Impact Requests to open external protocol URLs from web content did not take iframe sandbox restrictions into account, so a sandboxed iframe could cause an OS-registered external application to be launched. The frame's sandbox state was also not made available to the app's permission handlers. Ap...

CVE-2026-70612

The vulnerability CVE-2026-70612 affects Electron. It occurs when web content in sandboxed iframes can trigger external protocol handlers, because iframe sandbox restrictions were not applied to openExternal requests and the frame state wasn’t exposed to permission handlers. This could allow an O...

Command Injection

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 Command Injection in the DevTools embedder handler. An attacker can execute arbitrary files outside the sandbox by leveragi...

Electron: DevTools embedder handler executes arbitrary files via shell open

Impact The DevTools "reveal in file manager" action could launch the target file rather than reveal it. An attacker with a separate means of running script inside the DevTools frontend such as a malicious DevTools extension could use this to execute native code outside the sandbox. Apps are only...

Electron: contextBridge object copy honors prototype setters

Impact Objects copied across the contextBridge boundary from untrusted content could carry an attacker-influenced prototype, enabling prototype-pollution-style attacks against preload code despite context isolation being enabled. Apps are only affected if their preload code accepts object argumen...
