OpenClaw: Isolated cron awareness events were recorded as trusted system events

## Affected Packages / Versions - Package: `openclaw` (npm) - Affected versions: `< 2026.4.20` - Patched version: `2026.4.20` ## Impact Output from webhook-triggered isolated cron agent runs could be queued into the main session awareness stream without `trusted: false`. That made the event render as a trusted `System:` event instead of an untrusted system event. This is a trust-labeling issue that can strengthen prompt-injection impact, but it does not directly bypass gateway auth, tool policy, or sandboxing. Severity is low. ## Fix OpenClaw now preserves untrusted labels for isolated cron awareness events and forwards the trust flag through cron delivery helpers. Fix commit: - `f61896b03cc7031f51106a04566831f4ac2a0bd7` ## Release Fixed in OpenClaw `2026.4.20`.
