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 vulnerability in prolix-oc Lumiverse versions prior to 0. 9. 7. It involves improper neutralization of argument delimiters in a command, leading to argument injection. Specifically, when the primary toSmbPath(fullPath) call fails, the fallback method concatenates the basename directly into an smbclient command without proper validation. This allows an attacker to inject commands using special characters like ';' and '! '. The vulnerability enables arbitrary command execution on the Lumiverse server. This issue is fixed in version 0. 9.
AI Analysis
Technical Summary
Lumiverse, an AI chat application by prolix-oc, contains a command injection vulnerability (CWE-88) in versions before 0.9.7. When the toSmbPath(fullPath) function throws an error, the fallback logic splits the path into dirname and basename, validating only the directory prefix. The basename is then directly concatenated into an smbclient -c script without sanitization. Since smbclient interprets ';' as a subcommand separator and '!cmd' as a shell escape, an attacker can craft a basename containing "; !<cmd>; echo " to execute arbitrary commands on the server. This vulnerability has a CVSS 3.1 score of 9.1 (critical) and is fixed in Lumiverse 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 severity rating.
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 in the advisory, but the fix is stated to be in version 0.9.7.
