OpenClaw: QQ Bot structured payloads could read arbitrary local files

Summary

Before OpenClaw 2026.4.2, QQ Bot structured media payloads could read local files from attacker-chosen paths. A crafted structured payload could escape QQ Bot-owned media roots and cause arbitrary file reads on the host.

Impact

Prompt-influenced structured payload output could exfiltrate any host file readable by the OpenClaw process through the QQ Bot media-send path. This was a real confidentiality bug on the host filesystem boundary.
