Summary
Paperclip (@paperclipai/server) versions prior to 2026.416.0 contain a privilege escalation vulnerability that allows an attacker with an Agent API key to execute arbitrary OS commands on the Paperclip server host. Agents can update their own adapterConfig via the /agents/:id endpoint, and the adapterConfig.workspaceStrategy.provisionCommand field is later executed by the server during workspace provisioning.
Risk Assessment
An attacker with agent credentials can execute arbitrary shell commands on the server host, leading to remote code execution and system compromise. This breaks the trust boundary between agent configuration and host execution.
Recommendation
Update @paperclipai/server to version 2026.416.0, which fixes the vulnerability. Until updated, restrict agents' ability to modify adapterConfig and monitor for unusual provisioning commands.
Other vulnerabilities in Paperclip
See all- CVE-2026-77087Critical
Paperclip before 0.3.1 in default local_trusted mode fails to validate Host headers, allowing attackers to execute arbitrary commands via DNS rebinding. An attacker can craft a malicious webpage that, when visited by a developer running Paperclip locally, uses DNS rebinding to make authenticated API requests and execute commands through the process adapter.
- CVE-2026-119713High
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.
Original NVD description (English source)
Paperclip is a Node.js server and React UI that orchestrates a team of AI agents to run a business. Versions of @paperclipai/server prior to 2026.416.0 contain a privilege escalation vulnerability that allows an attacker with an Agent API key to execute arbitrary OS commands on the Paperclip server host. An attacker with an agent credential can escalate privileges from the agent runtime to the Paperclip server host. The vulnerability occurs because agents are allowed to update their own adapterConfig via the /agents/:id API endpoint. The configuration field adapterConfig.workspaceStrategy.provisionCommand is later executed by the server runtime. As a result, an attacker controlling an agent credential can inject arbitrary shell commands which are executed by the Paperclip server during workspace provisioning. This breaks the intended trust boundary between agent runtime configuration and server host execution, allowing a compromised or malicious agent to escalate privileges and run commands on the host system. This vulnerability allows remote code execution on the server host. @paperclipai/server version 2026.416.0 fixes the issue.
