Name of the Vulnerable Software and Affected Versions Lumiverse versions prior to 0.9.7

Description The Spindle extension build pipeline executes bun install without the --ignore-scripts flag before performing the static backend safety scan via the assertSafeBackendBundle() function. This allows a malicious extension containing a package.json file with preinstall, postinstall, or prepare lifecycle scripts to achieve host-level code execution when an administrator initiates the installation process, occurring before any distribution files are inspected.

Recommendations Update to version 0.9.7.
