CVE-2026-41208: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in paperclipai @paperclipai/server
CVE-2026-41208 is a high-severity OS command injection vulnerability in versions of @paperclipai/server prior to 2026. 416. 0. It allows an attacker with an Agent API key to escalate privileges by injecting arbitrary shell commands through the adapterConfig. workspaceStrategy. provisionCommand field. This leads to remote code execution on the Paperclip server host. The vulnerability arises because the server executes this provisionCommand without proper neutralization of special elements, breaking the trust boundary between agent runtime and server host. The issue is fixed in version 2026. 416.
AI Analysis
Technical Summary
The vulnerability in @paperclipai/server (CVE-2026-41208) involves improper neutralization of special elements in the adapterConfig.workspaceStrategy.provisionCommand field, which is executed by the server runtime during workspace provisioning. An attacker with an Agent API key can update this configuration via the /agents/:id API endpoint, injecting arbitrary OS commands. This results in privilege escalation from the agent runtime to the server host, enabling remote code execution. Versions prior to 2026.416.0 are affected, and the issue is resolved in 2026.416.0.
Potential Impact
An attacker possessing an Agent API key can execute arbitrary OS commands on the Paperclip server host, leading to full compromise of the server environment. This includes potential unauthorized access, data manipulation, and disruption of service. The vulnerability breaks the intended security boundary between agent runtime and server host execution, allowing privilege escalation and remote code execution with high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Upgrade @paperclipai/server to version 2026.416.0 or later, where this vulnerability is fixed. Since the vendor advisory confirms the fix in this version, applying this update is the recommended remediation. Patch status is not explicitly stated beyond this version, so verify with the vendor advisory for any additional guidance.
