概要

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.

NVD の説明

OpenClaw before 2026.3.28 downloads and stores inbound media from Zalo channels before validating sender authorization. Unauthorized senders can force network fetches and disk writes to the media store by sending messages that are subsequently rejected.
