Unknown · Mcpjam Inspector · CVE-2026-23744
**Name of the Vulnerable Software and Affected Versions**
MCPJam inspector versions prior to 1.4.3
**Description**
MCPJam inspector, a local-first development platform for MCP servers, contains a flaw that allows remote code execution (RCE). The software by default listens on 0.0.0.0 instead of 127.0.0.1, making its HTTP APIs remotely reachable. An attacker can send a crafted HTTP request to the '/api/mcp/connect' endpoint, which extracts the `command` and `args` variables without security checks, triggering the installation of an MCP server and leading to arbitrary command execution without user interaction.
**Recommendations**
Update to version 1.4.3.
Restrict access to the '/api/mcp/connect' endpoint to minimize the risk of exploitation.
