# CVE-2026-52873

> 6.9 MEDIUM · 🧪 PoC

## Beschreibung

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.
