CVE-2026-30617: n/a
LangChain-ChatChat 0.3.1 contains a remote code execution vulnerability in its MCP STDIO server configuration and execution handling. A remote attacker can access the publicly exposed MCP management interface and configure an MCP STDIO server with attacker-controlled commands and arguments. When the MCP server is started and MCP is enabled for agent execution, subsequent agent activity triggers execution of arbitrary commands on the server. Successful exploitation allows arbitrary command execution within the context of the LangChain-ChatChat service.
AI Analysis
Technical Summary
CVE-2026-30617 describes a remote code execution vulnerability in LangChain-ChatChat 0.3.1. The issue arises from the MCP STDIO server's configuration and execution handling, where the publicly exposed MCP management interface can be accessed by a remote attacker. The attacker can then configure the MCP STDIO server with attacker-controlled commands and arguments. When the MCP server is started and MCP is enabled for agent execution, these commands are executed, resulting in arbitrary command execution within the LangChain-ChatChat service context. This vulnerability allows remote attackers to execute arbitrary commands on the server running the vulnerable software.
Potential Impact
Successful exploitation results in arbitrary command execution on the server hosting LangChain-ChatChat 0.3.1. This can lead to full compromise of the affected system within the privileges of the LangChain-ChatChat service. There is no information about exploitation in the wild or additional impact details.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the MCP management interface to trusted users only and disable MCP agent execution if possible to reduce exposure.
