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 execute arbitrary OS commands on the Paperclip server host by injecting commands into the adapterConfig. workspaceStrategy. provisionCommand field via the /agents/:id API endpoint. This breaks the trust boundary between agent runtime configuration and server host execution, enabling privilege escalation from the agent runtime to the server host. The vulnerability is fixed in version 2026. 416. 0.
AI Analysis
Technical Summary
The vulnerability in @paperclipai/server (CVE-2026-41208) arises because agents can update their own adapterConfig, specifically the workspaceStrategy.provisionCommand field, which the server later executes. This improper neutralization of special elements (CWE-78) allows an attacker with an Agent API key to inject arbitrary shell commands, leading to remote code execution on the server host. The flaw enables privilege escalation from the agent runtime environment to the server host. Versions prior to 2026.416.0 are affected, and the issue is resolved in version 2026.416.0.
Potential Impact
An attacker possessing an Agent API key can exploit this vulnerability to execute arbitrary OS commands on the Paperclip server host, resulting in full compromise of the server environment. This includes privilege escalation from the agent runtime to the server host, potentially leading to complete control over the affected system. The CVSS score of 8.8 reflects 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 this is a self-hosted server product, administrators must apply the update to remediate the issue. Patch status is not explicitly stated in the vendor advisory, but the description confirms the fix is included in version 2026.416.0. No other mitigations are indicated.
