CVE-2026-30623: n/a
LiteLLM version 1.18.10 contains a critical remote code execution vulnerability in its MCP server creation functionality. The vulnerability arises because the application executes arbitrary commands and arguments specified in a JSON configuration without validation. This allows an attacker to run operating system commands with the privileges of the LiteLLM process. The vulnerability has a CVSS score of 9.8, indicating a critical severity level. No patch or official remediation has been confirmed at this time.
AI Analysis
Technical Summary
CVE-2026-30623 affects LiteLLM version 1.18.10 and involves a remote code execution vulnerability due to unsafe execution of user-supplied command and argument values in the MCP server creation feature. The application accepts a JSON configuration that specifies arbitrary commands and arguments, which are executed on the host system without validation or sanitization. This flaw corresponds to CWE-77 (Improper Neutralization of Special Elements used in a Command). Exploitation allows attackers to execute arbitrary OS commands remotely with the privileges of the LiteLLM process.
Potential Impact
Successful exploitation results in remote code execution with the privileges of the LiteLLM process, potentially allowing full system compromise depending on those privileges. The vulnerability impacts confidentiality, integrity, and availability of the affected system, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). There are no known exploits in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, avoid deploying LiteLLM version 1.18.10 in untrusted environments or restrict access to the MCP server creation functionality. Monitor vendor communications for updates and apply patches promptly once released.
