CVE-2026-44449 Details
Description
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 "; !<cmd>; echo " achieves arbitrary command execution on the Lumiverse server. This vulnerability is fixed in 0.9.7.
A vulnerability in Lumiverse, an AI chat application, allows for arbitrary command execution on the server. This issue exists in versions prior to 0.9.7. The vulnerability arises in the SMBFileSystem.exists() method, which improperly validates the basename of file paths. When the primary path validation fails, the method splits the path into directory and basename components. The basename, lacking proper validation, is directly appended to the smbclient command. Since smbclient treats certain characters as command separators or execution triggers, a crafted path can execute arbitrary commands on the Lumiverse server.
Users are advised to update Lumiverse to version 0.9.7 or later, where this vulnerability has been fixed.
