Short explanation

Paperclip versions from 2026.403.0 before 2026.416.0 contain a remote code execution vulnerability that allows agent API key holders to set cleanupCommand and teardownCommand via PATCH /api/execution-workspaces/:id.

Why does it matter?

An authenticated attacker with low privileges can execute arbitrary OS commands within the context of the Paperclip server process, compromising the server host.

What should be done?

  • Update the software to version 2026.416.0 or later
  • Follow vendor advisories
  • Review available patch references

Paperclip 2026.403.0 before 2026.416.0 contains a remote code execution vulnerability that allows agent API key holders to set cleanupCommand and teardownCommand via PATCH /api/execution-workspaces/:id. When the workspace is archived, cleanupExecutionWorkspaceArtifacts runs these commands through a shell as the Paperclip server process, executing attacker-chosen OS commands on the server host.
