Lumiverse is a full-featured AI chat application. Prior to 0.9.7, when the primary toSmbPath(fullPath) call throws, the method falls back to a dirname/basename split and only validates the directory prefix. The basename is concatenated directly into the smbclient -c script without validation. smbclient interprets ; as a subcommand separator and !cmd as a local-shell escape that runs cmd on the host. A path whose directory component is clean but whose basename contains "; ! ; echo " achieves arbitrary command execution on the Lumiverse server. This vulnerability is fixed in 0.9.7.

No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.
