Vulnetix · Advisory published March 1, 2026

Installs a persistent Puppeteer HTTP service at /opt/puppeteer-service/ listening on all interfaces (0.0.0.0:3001) without authentication, registered as a systemd service that persists across reboots. The service accepts Basecamp credentials via unauthenticated HTTP POST and uses them to log into Basecamp via browser automation. scripts/setup.js (postinstall) silently installs Chromium, creates a Puppeteer server.js at /opt/puppeteer-service/, installs /etc/systemd/system/basecamp-puppeteer.service with Restart=always, and starts the service. The service listens at 0.0.0.0:3001 without authentication and accepts {email, password, accountId, operation} via POST /basecamp to perform Basecamp browser automation.
