When an attacker supplies or alters tool metadata that contains malicious control characters, the terminal output can be manipulated.

The effect is loss of trust in terminal displays and logs, potentially leading to user deception or unintended approval of operations."}}}}, "created": "2026-04-13T12:44:24.017632+00:00", "updated": "2026-04-13T13:00:53.324265+00:00", "vendors": ["openclaw", "openclaw$PRODUCT$openclaw"]}
