Summary

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

Details

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.

Fix Commit(s)

3cb1a56bfc9579a0f2336f9cfa12a8a744332a19

Verification

The fix commit is contained in the public v2026.4.22 tag.
openclaw@2026.4.22 is published on npm and the compiled package contains the fix.
Focused regression coverage for this path passed before publication.

OpenClaw thanks @VladimirEliTokarev for reporting.
