GHSA-jr5w-w6x2-84p9 - Electron: Mitigation for compromised eMudhra intermediate certificates
### 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`
