CyberRota Analysis

AI-Generated

The vulnerability affects Streambert versions 2.5.0 to 2.6.0 on Windows, where the IPC handler improperly removes the Content-Security-Policy header, allowing for potential script injection from untrusted sources. This can lead to unauthorized access to application functionality and sensitive data, especially if combined with other vulnerabilities. Users of affected versions, particularly those handling sensitive information or using the Wyzie API key redemption feature, should prioritize updating to version 2.6.0 to mitigate risks.

Original NVD Description

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.
