CVE-2026-44449: CWE-88: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') in prolix-oc Lumiverse
CVE-2026-44449 is a critical command injection vulnerability in prolix-oc's Lumiverse AI chat application versions prior to 0.9.7. The issue arises when the toSmbPath(fullPath) call fails and the fallback method concatenates an unvalidated basename directly into an smbclient command script. This allows an attacker to inject shell commands via special characters like ';' and '! cmd', leading to arbitrary command execution on the Lumiverse server. The vulnerability is fixed in version 0.9.7.
AI Analysis
Technical Summary
Lumiverse versions before 0.9.7 contain an improper neutralization of argument delimiters (CWE-88) vulnerability. When the primary toSmbPath(fullPath) call throws an error, the fallback method splits the path into directory and basename components, validating only the directory prefix. The basename is then concatenated directly into an smbclient -c command script without validation. Since smbclient interprets ';' as a subcommand separator and '!cmd' as a local shell escape, an attacker can craft a basename containing "; !<cmd>; echo " to execute arbitrary commands on the server hosting Lumiverse. This vulnerability has a CVSS 3.1 score of 9.1, indicating critical severity, and was fixed in Lumiverse version 0.9.7.
Potential Impact
Successful exploitation allows an attacker with high privileges to execute arbitrary commands on the Lumiverse server, potentially leading to full system compromise, data theft, or disruption of service. The vulnerability affects confidentiality, integrity, and availability with a critical impact level.
Mitigation Recommendations
This vulnerability is fixed in Lumiverse version 0.9.7. Users should upgrade to version 0.9.7 or later to remediate this issue. No other official remediation or temporary fixes are documented. Patch status is not explicitly confirmed beyond the fix in 0.9.7; verify with the vendor advisory for the latest guidance.
