| Doc Text: |
A flaw was found in electron-updater, a component used for automatic updates in Electron applications. This vulnerability allows a remote attacker to obtain sensitive user credentials. When an Electron application performs an HTTP redirect, the electron-updater's redirect handler fails to strip certain credential-bearing headers, such as PRIVATE-TOKEN or mixed-case Authorization headers. This oversight can lead to these credentials being forwarded to an attacker-controlled destination, resulting in information disclosure.
