What is CVE-2026-44444?

A code execution vulnerability exists in the Lumiverse AI chat application due to the Spindle extension build pipeline invoking 'bun install' without the '--ignore-scripts' flag. This flaw allows a malicious extension that includes a package.json with lifecycle scripts (preinstall, postinstall, or prepare) to execute host-level code as soon as an administrator initiates the installation process, prior to any distribution files being checked. This serious security risk has been addressed in version 0.9.7 of Lumiverse.

Affected Version(s)
