Chromium may require Local Network Access permission for pages served from public origins. Local-origin pages and other delivery paths are not consistently subject to this restriction. The /api/launch endpoint accepts an attacker-selected emulatorPath if it points to an existing file on the victim’s host. On POSIX systems, that file must also be executable. The endpoint additionally requires an existing ebootPath . The /api/command endpoint exposes…
