Upgrade electron-updater to version 6.3.0-alpha.6 or higher.
Overview
electron-updater is a module allowing applications to implement auto-update functionality.
Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature through the windowsExecutableCodeSignatureVerifier process. An attacker in control of an update manifest - via server compromise or other exploitation - can bypass signature verification of a downloaded file by tricking the application into verifying the signature on a different file instead.
Note: This is only exploitable on Windows.
