OpenClaw before 2026.3.24 contains a sandbox bypass vulnerability in the message tool that allows attackers to read arbitrary local files by using mediaUrl and fileUrl alias parameters that bypass localRoots validation. Remote attackers can exploit this by routing file requests through unvalidated alias parameters to access files outside the intended sandbox directory.
