CVE-2026-44450: Lumiverse MCP server endpoint allows authenticated remote code execution

In the Lumiverse AI chat application prior to version 0.9.7, the MCP server creation endpoint validated only the command binary name against an allowlist while passing the args array unchecked to a child process, letting any logged-in user run arbitrary OS-level code via inline-execution flags. The server listened on all interfaces and its host-header rebinding check could be trivially bypassed, making the flaw exploitable from any machine with network access; it is fixed in 0.9.7.

Impact

Any authenticated user (owner privileges not required) could achieve arbitrary operating-system code execution on the Lumiverse server, exploitable remotely from any host able to reach the server port.
