CVE-2026-41679 is a critical authorization bypass in Paperclip that affects network-accessible deployments running in authenticated mode with the default registration configuration prior to version 2026.416.0. The flaw arises from multiple trust and authorization failures in the account onboarding and company import workflow. A remote attacker can self-register without email verification, create a CLI authorization challenge, approve that challenge using the same newly created account, and obtain a persistent board-level API credential without an independent approver. Paperclip correctly restricted direct creation of a new company to instance administrators, but the equivalent company import path accepted only board-level access. By abusing that mismatch, an attacker can import a crafted company bundle containing a .paperclip.yaml configuration that defines an agent using Paperclip’s built-in process adapter. When the imported agent is awakened, Paperclip launches the attacker-specified command as a child process on the host, resulting in full remote code execution with the privileges of the Paperclip server process. The attack is described as fully automated, requiring six API calls and no user interaction or pre-existing credentials.

This repository is a small Python proof-of-concept exploit for CVE-2026-41679 affecting Paperclip AI. The repo contains one executable script (poc.py), a short README with usage instructions, and a minimal requirements.txt listing requests. The exploit is not framework-based. The script performs a full exploitation chain against a target Paperclip instance over HTTP(S): it signs up a user, signs in to obtain a session cookie, creates a CLI auth challenge, approves that challenge with the authenticated session, then uses the returned board API token to call the company import API. In that import request it supplies inline files including COMPANY.md, agents/pwn/AGENTS.md, and a malicious .paperclip.yaml. The YAML defines an agent named pwn using a process adapter configured to run bash with '-c' and attacker-controlled commands. After import, the script calls the agent wakeup endpoint to trigger execution. The exploit’s main capability is authenticated remote command execution through abuse of the import and agent execution workflow. The default payload writes the output of 'id' and 'whoami' to /tmp/pwned.txt, but the -c argument allows arbitrary shell commands, making this more than a pure detector. TLS certificate verification is explicitly disabled, so it will also work against instances with self-signed certificates. Overall, this is an operational PoC that automates exploitation end-to-end and demonstrates code execution on the target host.
