Affected: npm: openclaw

## Summary

The Zalo image path fetched and stored inbound media before the DM/pairing authorization checks ran.

## Impact

Unauthorized senders could force network fetches and disk writes in the inbound media store even when the message itself was rejected.

## Affected Component

`extensions/zalo/src/monitor.ts`

## Fixed Versions

- Affected: `<= 2026.3.24` - Patched: `>= 2026.3.28` - Latest stable `2026.3.28` contains the fix.

## Fix

Fixed by commit `68ceaf7a5f` (`zalo: gate image downloads before DM auth`).

OpenClaw thanks @AntAISecurityLab for reporting.
