Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Electron versions before 42.11.16, from 43.0.0-alpha.1 up to 43.8.1, from 44.0.0-alpha.1 up to 44.9.1, and from 45.0.0-alpha.1 up to 45.0.0-beta.6 are affected by a mitigation for compromised eMudhra intermediate certificates. An attacker who holds a certificate issued through those intermediates and can intercept network traffic could impersonate a TLS server to an app, and only apps that make TLS connections over a network an attacker can intercept are affected. Upgrade to 42.11.16, 43.8.1, 44.9.1, or 45.0.0-beta.6 or later, since no app-side workaround exists.
