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