GHSA-846p-hgpv-vphc OpenClaw: QQ Bot structured payloads could read arbitrary local files

• npm openclaw: < 2026.4.2 → fixed in 2026.4.2

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.
