Summary
Duplicate Advisory: OpenClaw: MCP loopback owner context is derived from server-issued bearer tokens
Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-r6xh-pqhr-v4xh. This link is maintained to preserve external references.

Original Description

OpenClaw before 2026.4.22 derives loopback MCP owner context from spoofable server-issued bearer tokens in request headers. Non-owner loopback clients can present themselves as owner to bypass owner-gated operations by manipulating the sender-owner header metadata.
