Technical details
The MCP server launched by `trigger dev --mcp` binds to all network interfaces (0.0.0.0) without hostname restriction and exposes /sse and /messages endpoints with no authentication middleware. An attacker on the LAN or a malicious webpage visited by the developer can send JSON-RPC 2.0 MCP tool requests to invoke trigger-task, cancel-run, list-runs, and get-run-logs, all of which execute against the developer's stored Trigger.dev access token bound at server construction.
Affected products
- Trigger.dev cli-v3 3.0.0 before 4.5.4
