Streambert is a cross-platform Electron Desktop App to stream and download video content. From version 2.5.0 until version 2.6.0, the wyzie-open-redeem IPC handler in index.js creates the partition:wyzie-redeem Electron session and registers an onHeadersReceived hook that removes the Content-Security-Policy header from every response in that session. The redeem window also lacks a setWindowOpenHandler restriction, so script injection in sub.wyzie.io, a loaded third-party resource, or a site reached through navigation executes without CSP constraints and can affect additional windows and persistent session storage. A user must open the Wyzie API key redemption window, and exploitation requires attacker-controlled script content in a loaded page. The resulting renderer script can invoke renderer-exposed application functionality and can be chained with other vulnerabilities to access internal services or sensitive data. This issue is fixed in version 2.6.0.

No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.
