Critical Vulnerability in NestJS Devtools: Localhost RCE via Sandbox Escape
A flawed sandbox in @nestjs/devtools-integration lets attackers run code on your machine via CSRF, leading to full Remote Code Execution (RCE).
Quickly evaluate the security and health of any open source package.
fdc3-web-monorepo
2.1.0

Removed from npm
Blocked by Socket
The code contains data exfiltration functionality that collects sensitive system information including home directory, hostname, username, and DNS server details, then sends this data via HTTPS POST request to 4glx4u23zwe4z6iu1x1vp6hvgmmdaby0[.]oastify[.]com without user consent. This behavior is consistent with malware attempting to gather system reconnaissance data.

Live on npm
Blocked by Socket
This package is malicious software masquerading as a legitimate LinkedIn badge component. It systematically collects sensitive user data including IP addresses and browser information, then transmits this data to unauthorized third-party servers. The heavy obfuscation and use of non-LinkedIn domains for supposed LinkedIn functionality are clear indicators of malicious intent. This constitutes data theft and unauthorized surveillance.
jcinvcc
1.0.9
by kkya2022
Removed from npm
Blocked by Socket
This file contains code that renders a UI component displaying hardcoded sensitive credentials (passwords, SIP credentials, server details) and explicitly instructs users to copy and paste these values to a suspicious external website at http://47[.]94[.]156[.]96:5049. The presence of these credentials and the unusual pattern of directing users to an IP-based URL on a non-standard port represents a significant security risk. While the code doesn't directly exfiltrate data through network requests, it facilitates credential harvesting through user action, effectively functioning as a social engineering attack embedded in the code. The suspicious destination IP address and exposed authentication details suggest this is an intentional attempt to capture credentials or enable unauthorized access.

The 'index.js' file contains malicious code that poses serious security threats. It reads sensitive system files such as '/etc/passwd' and '/etc/hosts', encodes their contents in base64, and sends this data to a remote server at 'fixing[.]my' via an HTTP POST request using 'curl'. Additionally, the code attempts to establish a reverse shell connection to the IP address '95.111.250.209' using 'telnet', potentially allowing unauthorized remote access and control over the affected system.

This is an area that I have personally been very focused on. As Nat Friedman said in the 2019 GitHub Universe keynote, Open Source won, and every time you add a new open source project you rely on someone else code and you rely on the people that build it.
This is both exciting and problematic. You are bringing real risk into your organization, and I'm excited to see progress in the industry from OpenSSF scorecards and package analyzers to the company that Feross Aboukhadijeh is building!
