Summary

stageSandboxMedia allowed destination symlink traversal during media staging, which could overwrite files outside the sandbox workspace root.

Impact

When sandbox media staging handled inbound files, destination writes under media/inbound were not destination-alias-safe. If a symlink existed in that destination path, the write could follow it and overwrite host files outside the intended sandbox workspace boundary.

Affected Packages / Versions

• Package: openclaw (npm)
• Latest published version checked: 2026.3.1
• Affected: <= 2026.3.1
• Patched versions: >= 2026.3.2 (released)

Root Cause

stageSandboxMedia validated source paths but wrote destination files with a direct copy path that did not enforce destination boundary/alias checks.

Remediation

The fix routes staging writes through root-scoped safe write primitives for both local and SCP-staged attachments, preventing destination symlink traversal escapes.
