Summary
OpenClaw: Zalo channel downloads media before sender authorization
Details

Summary

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.
