Description

--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (936d3c8bc6611b58f5321ba5aab651bb3d2db821d172816283ca04633be00863) The `stella` CLI shipped in bin/stella.js prompts users for their phone number and the WhatsApp verification code and POSTs both to a hardcoded bare-IP plain-HTTP endpoint at http://62.238.2.22:8787 (paths /api/v1/auth/register/register and /verify). Subsequent chat input is sent to the same host. There is no disclosure that authentication credentials leave the user's machine to an anonymous IPv4 address unrelated to the advertised homepage stella-ai.app. In addition, bin/postinstall.js and install.bat implement a dropper flow that downloads stella-latest.tar.gz from the same bare-IP plain-HTTP endpoint, extracts it under ~/.stella, installs the Bun runtime via `curl -fsSL https://bun.sh/install | bash`, and executes the fetched contents; the Windows bootstrap pipes http://62.238.2.22:8787/install.ps1 directly into `iex`. The download URL is mutable, unpinned, unverified, and served over cleartext from an anonymous IPv4 address, so whatever bytes the endpoint currently serves execute with the user's privileges. Package metadata reinforces the mismatch: homepage stella-ai.app, repository github.com/anomalyco/opencode, operational endpoint a raw IPv4. ## Source: ghsa-malware (042a564970d9ea4747ece2d03fa02b3acf2085e515df00bf24153eeac0c698d7) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

Impact

User credentials (phone number and WhatsApp verification code) are exfiltrated to an anonymous IP address without disclosure, risking account compromise. The package also executes arbitrary code fetched from an untrusted source over unencrypted HTTP, enabling potential full system compromise under the user's privileges. This malicious behavior undermines user trust and can lead to data theft, unauthorized access, and further malware infection.

Defensive guidance

Users should immediately discontinue use of stella-ai-cli versions 2.0.0 and 3.0.1. Avoid installing or running this package. Since the package downloads and executes code from an untrusted source, manual removal and system inspection for compromise are recommended. Monitor official advisories for updates or fixes.

Summary

The stella-ai-cli package (versions 2.0.0 and 3.0.1) includes a CLI tool that prompts users for sensitive authentication information (phone number and WhatsApp verification code) and sends these to a hardcoded bare-IP HTTP endpoint (http://62.238.2.22:8787) unrelated to the official homepage. The package's post-install scripts download and execute code from this same untrusted endpoint without integrity verification, including executing a PowerShell script directly from the network on Windows systems. This results in arbitrary code execution with the user's privileges and unauthorized data exfiltration.
