Verified Advisory
Arbitrary binary execution via IPC handler in Streambert (CVE-2026-48056)
The `run-download` IPC handler in Streambert accepts an arbitrary executable path (`binaryPath`) from the renderer process and spawns it via Node's `spawn` without any path validation. A compromised renderer process - for example through XSS or remote feed injection - can exploit this handler to execute arbitrary local binaries (such as `cmd.exe` or `powershell.exe`) with the privileges of the Streambert desktop application. The vulnerability is located in `src/ipc/downloads.js`.
Affected versions:
- <= 2.4.0
We recommend updating to: >= 2.5.0.
