Vulnerability details
The vulnerability allows a remote user to execute arbitrary OS commands on the server host.
The vulnerability exists due to command injection in the workspace provisioning command handling in server/src/services/workspace-runtime.ts when processing agent-controlled adapterConfig.workspaceStrategy.provisionCommand during workspace provisioning. A remote user can update agent configuration and trigger workspace provisioning to execute arbitrary OS commands on the server host.
Exploitation requires an Agent API key and can be triggered through the PATCH /api/agents/:id and POST /api/agents/:id/wakeup API endpoints.
