SCA: security update for @mcpjam/inspector (GHSA-232v-j27c-5pp6)

critical Tenable Self-Hosted Container Security Plugin ID 436809

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - MCPJam inspector is the local-first development platform for MCP servers. Versions 1.4.2 and earlier are
 vulnerable to remote code execution (RCE) vulnerability, which allows an attacker to send a crafted HTTP
 request that triggers the installation of an MCP server, leading to RCE. Since MCPJam inspector by default
 listens on 0.0.0.0 instead of 127.0.0.1, an attacker can trigger the RCE remotely via a simple HTTP
 request. Version 1.4.3 contains a patch. (CVE-2026-23744)
