Lumiverse is a full-featured AI chat application. Prior to 0.9.7, the MCP server creation endpoint validates the command field against an allowlist of binary names but forwards the args array to the child process without any validation. Every binary on the allowlist accepts an inline-code execution flag (-e for node/bun, -c for python3/deno), giving any logged-in user arbitrary OS-level code execution on the Lumiverse server. The route requires only requireAuth (not requireOwner). The server binds on all interfaces (::) and the host-header rebinding check is bypassed trivially by any HTTP client that sends Host: localhost:<port> directly, making this exploitable from any machine with network access to the server port. This vulnerability is fixed in 0.9.7.
AnalysisAI
Remote code execution in Lumiverse AI chat application prior to 0.9.7 allows any authenticated user to run arbitrary OS-level commands on the server by abusing the MCP server creation endpoint. Although the endpoint allowlists binary names (node, bun, python3, deno), it forwards user-controlled args unfiltered to the child process, and every allowed binary supports inline code execution flags (-e or -c). …
