Summary

MCP loopback owner context is derived from server-issued bearer tokens.

Affected Packages / Versions

• Package: openclaw (npm)
• Affected versions: <= 2026.4.21
• Fixed version: 2026.4.22

Impact

The loopback MCP path accepted spoofable owner-context metadata from request headers, which could allow a non-owner loopback client to present itself as owner for owner-gated operations.

Fix

The MCP loopback runtime now issues separate owner and non-owner bearer tokens and derives senderIsOwner exclusively from which token authenticated the request. The spoofable sender-owner header is no longer emitted or trusted.
