OpenClaw's message tool media parameter bypasses tool policy filesystem isolation
Summary
The message tool accepted mediaUrl and fileUrl aliases without applying the same sandbox localRoots validation as the canonical media path handling.
Impact
A caller constrained to sandbox media roots could read arbitrary local files by routing them through the alias parameters.
Affected Component
