Summary

Paperclip 2026.403.0 before 2026.416.0 contains a remote code execution flaw in the @paperclipai/server package, tracked as CWE-78. An attacker holding an agent API key can set cleanup and teardown commands through the workspace API, and the server runs them through a shell with the server process's privileges when the workspace is archived. The commands run on the server host, so the attacker can execute arbitrary operating system commands there.
