OpenClaw: Feishu extension resolveUploadInput bypasses file-system sandbox and allows arbitrary file reads via upload_image

Summary

Feishu upload path resolution could read files outside the configured localRoots sandbox before handing them to the upload path.

Impact

A tool caller constrained to workspace or localRoots paths could exfiltrate arbitrary host files through Feishu upload actions.

• Patched: >= 2026.3.28
