Summary
Malicious code in strapi-plugin-listcc-meeb (npm)
Details

strapi-plugin-listcc-meeb@3.6.8 declares scripts.postinstall = 'node postinstall.js' (and points main at the same file), so npm install auto-executes postinstall.js. That script spawns a Python one-liner via child_process that opens a socket to the hardcoded IP 14.225.210.85:80 and attaches a PTY-backed /bin/sh to the remote peer, yielding an interactive reverse shell on the installer's host. Execution is gated only by a hostname check ('ubuntu-fc-uvm'). Package metadata masquerades as a Strapi plugin ('Strapi plugin for enhanced functionality') while the repository/homepage is a placeholder github.com/user/... URL and the shipped code contains no plugin functionality — only the reverse-shell payload.

CWE
  • CWE-506 - The product contains code that appears to be malicious in nature.
