CVE-2026-44444

Lumiverse, an AI chat application, is vulnerable to host-level code execution in versions before 0.9.7 when a malicious extension includes harmful npm lifecycle scripts. The flaw occurs because the Spindle extension build pipeline runs bun install without the --ignore-scripts flag before a safety scan. This issue is resolved in Lumiverse version 0.9.7.
