Executive Summary

OpenClaw versions 2026.4.9 before 2026.4.10 contain a sender policy bypass vulnerability in the outbound host-media attachment read helper. This flaw allows attackers who have restricted read access via toolsBySender or group policy to bypass sender and group-scoped authorization boundaries.

By triggering host-media attachment loading, these attackers can retrieve readable local files through the outbound media path, leading to unauthorized local file disclosure.

The vulnerability is classified under CWE-863 (Incorrect Authorization) and was fixed in version 2026.4.10.

Impact Analysis

This vulnerability can allow an attacker with limited read permissions to bypass sender and group policy restrictions and access local files that should be protected.

Such unauthorized local file disclosure can lead to exposure of sensitive or confidential information stored on the affected system.

Because the attacker can retrieve files through the outbound media path, this could result in data leakage outside the intended security boundaries.

Mitigation Strategies

To mitigate this vulnerability, you should immediately update OpenClaw to version 2026.4.10 or later, where the issue has been fixed.

The fix ensures proper enforcement of sender identity and policy during outbound host-media attachment reads, preventing unauthorized local file disclosure.

Applying this patch will close the sender policy bypass and restore correct authorization boundaries.
