Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 42.11.16, 43.8.1, 44.9.1, and 45.0.0-beta.6, Electron does not block compromised eMudhra intermediate certificates in Chromium networking, Node.js tls, Node.js https, or Node.js fetch. An attacker who holds a certificate issued through one of these intermediates and can intercept network traffic can impersonate a TLS server to an affected application. This issue is fixed in versions 42.11.16, 43.8.1, 44.9.1, and 45.0.0-beta.6.

Affected: npm: electron

### Impact

A set of eMudhra intermediate certificates were compromised and are being blocked by browsers and other TLS clients. This Electron update adds the same block to both Chromium networking and Node.js `tls`, `https` and `fetch`. On earlier versions, an attacker holding a certificate issued through these intermediates and able to intercept network traffic could impersonate a TLS server to an app.

Apps are only affected if they make TLS connections over a network an attacker can intercept. Apps that make no network connections are not affected.

Other software has shipped the same mitigation, including Go (CVE-2026-111943) and Firefox (CVE-2026-113470).

### Workarounds

There are no app side workarounds, you must update to a patched version of Electron.

### Fixed Versions

* `45.0.0-beta.6` * `44.9.1` * `43.8.1` * `42.11.16`
