OpenClaw Sandbox Bind Validation Bypass Vulnerability

A vulnerability exists in OpenClaw versions prior to 2026.2.24, allowing attackers to bypass sandbox bind validation checks. This is achieved by exploiting symlinked parent directories with non-existent leaf paths, creating a scenario where bind source paths appear to be within allowed roots but actually resolve outside sandbox boundaries once the missing components are created. This exploitation weakens the enforcement of bind-source isolation in the sandbox environment.

Impact

Exploitation of this vulnerability can lead to unauthorized access to blocked runtime paths, weakening the isolation provided by the sandbox for bind sources.

Reproduction

To reproduce this vulnerability, create a symlinked directory that points to a non-existent leaf path outside of the allowed root. When the missing leaf is created, the bind source will resolve outside the sandbox boundaries, bypassing the validation checks.

Remediation

Users can update to OpenClaw version 2026.2.24 or later, where this vulnerability has been patched.
