OS Command Injection in Lumiverse (CVE-2026-44444)
Summary
OS command injection in Lumiverse (CVE-2026-44444). Successful exploitation can lead to full system takeover. Mitigation: upgrade to 0.9.7 or later.
Original description
The description as published by the source.
Lumiverse is a full-featured AI chat application. Prior to 0.9.7, the Spindle extension build pipeline calls bun install without the --ignore-scripts flag before running the static backend safety scan (assertSafeBackendBundle). A malicious extension that ships a package.json with a preinstall, postinstall, or prepare lifecycle script achieves host-level code execution the moment an admin presses Install before any dist file is inspected. This vulnerability is fixed in 0.9.7.
