Remote Code Execution on MCPJam Inspector <= 1.4.2
CVE-2026-23744 is a critical vulnerability in MCPJam Inspector (versions <= 1.4.2) that allows for unauthenticated Remote Code Execution (RCE).The flaw exists because the application's internal API server binds to all network interfaces (0.0.0.0) by default and lacks authorization on the /api/mcp/connect endpoint. An attacker can send a crafted JSON payload to this endpoint to execute arbitrary commands under the privileges of the user running the Inspector.
