OpenClaw: Lower-trust background runtime output is injected into trusted `System:` events, and local async exec completion misses the intended `exec-event` downgrade
Impact
Lower-trust background runtime output is injected into trusted System: events, and local async exec completion misses the intended exec-event downgrade.
Lower-trust runtime/background output could be promoted into trusted System events, allowing prompt-injection into later agent turns.
