OpenClaw: QQ Bot structured payloads could read arbitrary local files
Date: 2026-04
Affected: npm/openclaw
Attack vector: path-traversal
Category: vulnerability-disclosure
Severity: Medium
CWE: CWE-22

## 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. ## Affected Packages / Versions - Package: `openclaw` (npm) - Affected versions: `<= 2026.4.1` - Patched versions: `>= 2026.4.2` - Latest published npm version: `2026.4.1` ## Fix Commit(s) - `2c45b06afdd6f7c621038b5419d8e661cff34a7f` — restrict QQ Bot structured payload local paths ## Release Process Note The fix is present on `main` and is staged for OpenClaw `2026.4.2`. Publish this advisory after the `2026.4.2` npm release is live. Thanks @feiyang666 of Tencent zhuque Lab (https://github.com/Tencent/AI-Infra-Guard) for reporting.
