CVSS 3.1
Description
Paperclip is a Node.js server and React UI that orchestrates a team of AI agents to run a business. Prior to version 2026.416.0, an unauthenticated attacker can achieve full remote code execution on any network-accessible Paperclip instance running in `authenticated` mode with default configuration. No user interaction, no credentials, just the target's address. The chain consists of six API calls. The attack is fully automated, requires no user interaction, and works against the default deployment configuration. Version 2026.416.0 patches the issue.
