Name of the Vulnerable Software and Affected Versions OpenClaw versions prior to 2026.2.24

Description OpenClaw versions before 2026.2.24 contain a local media root bypass in the sendAttachment and setGroupIcon message actions when sandboxRoot is not configured. This allows attackers to read arbitrary host files accessible by the runtime user by hydrating media from local absolute paths. The vulnerability occurs because of bypassed local media root checks when sandboxRoot is unset.

Recommendations Upgrade to OpenClaw version 2026.2.24 or later.
