## Affected

- truelockmc streambert: fixed in 2.5.0

## Description

Streambert is a cross-platform Electron Desktop App to stream and download video content. Versions prior to 2.5.0 improperly validate executable paths supplied to the run-download IPC handler, allowing a compromised renderer process to execute arbitrary local binaries with the application’s privileges. Version 2.5.0 contains a patch.

## What to do

- Check your stack: if you ship or depend on truelockmc streambert, upgrade to a fixed version (2.5.0) per the references below.
