CVE-2026-44118: OpenClaw < 2026.4.22 - Owner Context Spoofing via Bearer Token Header

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.
