CVE-2025-27554Public exploitNetwork attack vector

Build server command execution via postinstall scripts

Published Mar 1, 2025 · Updated Mar 4, 2025

Code injection in ToDesktop for Electron before 2024-10-03 allows remote authenticated users to execute commands on its build server. The hosted builder executes an application's package.json postinstall script inside an overprivileged container able to read full-scope Firebase credentials. A ToDesktop account and submitted application are required; exploitation exposes platform secrets and enables unauthorized updates to hosted apps.
