CVE-2026-44444

Lumiverse prior to 0.9.7 has a vulnerability in the component override system that transpiles TSX via Sucrase and executes it with new Function, shadowing dangerous globals. Static protection and shadowing are bypassed by reconstructing identifiers from string fragments and DOM sandbox escape. A malicious theme pack (.lumitheme) can execute code in an authenticated user's session.

Vulnerability in Lumiverse (AI chat app) before version 0.9.7 allows a logged-in user to execute arbitrary code on the server via the MCP server creation endpoint. The attacker can use -e or -c flags in args, leading to remote code execution. The server listens on all interfaces and host-header rebinding protection is easily bypassed.

Lumiverse before version 0.9.7 contains a command injection vulnerability in the SMB path handling function. When the primary toSmbPath method fails, the code uses an unvalidated basename in the smbclient script, allowing arbitrary command execution via injection of ';' separator or '!cmd' local escape.

In Lumiverse before version 0.9.7, the consumeNonce() function does not validate any value from the incoming HTTP request or bind the nonce to the admin's session. If the admin's sign-up fails before the before hook fires (e.g., due to a duplicate email), the nonce remains set and can be used by an attacker within a 10-second window to register an unauthorized account.
